The Engineering Projects

Hi learners! I hope you are doing great. Today, I am going to share the second version(V2.0) of the LCD library for Proteus. We have already shared the LCD V1.0 Library on our blog. Along with appreciation, we also get some complaints/suggestions about that library. So, we have designed a better version of the LCD library by keeping the suggestions in mind.

Version 2.0 has error-free working, better pinout prints, and is identical to the real-world LCD. We have also removed our website link from the LCD. This library includes two alphanumeric LCDs in it i.e. LCD 16x2 and LCD 20x4.

If you don't have any experience with the LCD, no need to worry as we will guide you from scratch. Before installing the LCD, let's first have a look at its brief introduction:

What is Liquid Crystal Display?

• A liquid crystal display or LCD is a flat board of liquid crystals that are sandwiched between polarizers. When the electric field is applied to it, this material rotates according to the polarization and allows the light to pass through it. As a result, the display is shown on the LCD board.
• A simple 16x2 LCD is shown in the below figure:

• The LCD is used in electrical/electronic projects to display sensors' data, statuses, alerts, notifications etc.
• We can interface this LCD with any microcontroller i.e. Arduino, PIC, Atmel, Raspberry Pi, STM32 etc.
  
• Some of the advantages are low power consumption, durability, and long life.

Let's have a look at the pinout of LCD:

LCD Pinout

Both of these LCDs(16x2 and 20x4) have similar pinouts and a simple basic circuit needs to be designed in order to operate them. There are a total of 16 pins present in LCD used for different purposes. The below table has the complete description of LCD Pinout:

A student's academic career is full of writing assignments on different topics. This is so because assignments help students to learn and grow. Writing assignments throughout their academic career will not only contribute to increasing their knowledge but also develop skills that will be beneficial in both their academic career and practical life. 

However, students can only experience these benefits, if they start writing incredible assignments. Writing good assignments is not an easy task to do, it requires a proper approach to follow. Don’t worry, we have got you covered.  

In this blog post, we are going to explain a step-by-step procedure that will help academic students in writing incredible assignments. So, without discussing any other information, let’s head toward the steps.

How to Write Good Assignments – Step-by-Step Guide

Below are steps that you need to follow to write good assignments. Every step has own its importance, so it would be if you properly follow all of them. 

1. Understand and research the topic

The very first step students need to do is to get understand the given assignment topic. This involves what it is about, what kind of audience it will have, and many more. This will allow the students to tailor their assignments according to the topic.

After getting a proper understanding of the topic, you then need to start researching . This is essential to do because it allows students to gain a deeper understanding of the knowledge that needs to the discussed in the assignment. In simple words, doing research will allow them to gain expertise on the topic on which they are going to write an assignment. 

In order to perform efficient research, academic students need to read out all the pre-existing material about the topic. However, it is essential to read material that is from credible sources. 

Moving on, students should not stick to only one or two sources (no matter if they are highly credible). Instead, they should consider reading a number of sources, so that they can knowledge about the topic as much as possible. 

2. Collect facts and figures

After getting all the necessary information, students then start finding facts and figures about the topic. Adding these to the assignment will help them in backing up the claims they are going to make in the assignment. Generally, facts and figures are the ones that greatly help in grabbing user attention.

This is why, collecting facts and figures is an essential step towards writing good-quality assignments. To collect facts and figures, students should opt for trusted and authoritative sources. Not just this, they also need to ensure the statistics they are adding are updated. Because adding outdated or old stats can lead to inaccurate information. 

One more thing that they need to remember in this step is not to add statistics from the same source multiple times. This will make the teacher think that the students have written the assignment by using only one credible source. 

Tip: It would be good if students note down all the facts and figures separately so that they can forget any of them during the writing process.  

3. Create an outline 

Next, they need to create an outline for the assignment. The outline will act as a skeleton for the entire assignment process. Outlining the assignment will make it quite easy for students to organize their thoughts and ideas.

Moving on, it will also allow them to determine how they will make a connection between the things that are going discussed in the assignment. 

Apart from this, creating an outline will also the academic students to determine which points in the assignment need to be discussed in detail, and which are not.  

Note: While creating an outline, students need to ensure that all added points are completely relevant to the main topic. 

4. Start writing the introduction

From this step, most of the students will start struggling. But for the ones who have followed the previous steps properly, this step will not cause any hassle.

But remember, no student should not take an introduction less seriously. In fact, it will act as a pitch for the rest of the assignment. The introduction will decide whether the reader should continue reading or not. This is why, it needs to be written with the right approach.

A good introduction is one, that provides readers with a quick yet effective overview of the topic, and what you are going to discuss in it. However, remember not to provide all the necessary information only an introduction. Instead, students should need to keep it short and interesting.

There are a number of things that students can try in order to write an intro that will keep the readers interested in the assignment. Some of those things are as follows:

• Ask questions

• Mention problems related to the topic

• Mention you have got the solution

5. Write the main body in a proper format

In this step, the time and effort students have spent on research, collecting statistics, and outlining will come into play.

In the main body of the assignment, students need to expand all the points that were mentioned in the outline and introduction. Besides this, they also need to back up all the points with supportive statistics (that they have already gathered). 

However, when writing the main body of the assignment, they need to follow a proper structure or format. So that, the teacher can easily skim the given information. Properly formatting the main body includes, dividing the entire assignment into short paragraphs.

Students can also consider making use of bullets, lists, numbering, tables, charts, etc in order to efficiently format the assignment. 

Writing the main body by following a proper format will result in incredible assignments, and increasing the chances of getting appreciation from the teacher.

6. Conclude the assignment

After writing the main body, students then need to end the assignment with a concluding statement. Students need to write the conclusion in a way that, it provides a summarized overview of all the arguments made in the assignment.

Apart from this, the conclusion should also provide the readers with the personal thoughts or ideas of the writer about the given topic. 

7. Add a Reference page

At last, students need to add a reference page at the end of the assignment. This is also an essential step because it’s obvious that students will use information from already existing sources such as research papers, blogs, etc. So, it is necessary to mention the used sources at the end, this will leave a good impression that the student has done thorough research before writing.

A reference page will contain information about all the sources used in the assignment. This may include the author’s name, website name, publication date, etc. 

So, these are the steps that you need to follow in order to write incredible assignments.  

Useful Tips

Apart from the steps mentioned above, there are also some useful tips that academic students need to consider to write good assignments. 

1. Ensure you have followed the outline efficiently

Once a student has written the assignment, they need to confirm whether they have discussed everything according to the outline. Because sometimes, during the writing process, there are chances that students may accidentally skip a point or heading that was mentioned in the outline. This will result in disappointment and frustration. 

So, to avoid later regret, it would be good for students to ensure that they have followed the outline properly after the completion of the assignment. 

2. Check for plagiarism issues and resolve them

Another useful tip that students should follow is to check the written assignment for plagiarism issues. Plagiarism is a serious problem for students, it involves using someone else text without giving credit to the original author. It can occur both intentionally and intentionally and can have severe consequences like damaged academic reputation, low marks, etc. 

Therefore, it is necessary for students to check plagiarism issues. This can be done by utilizing an online plagiarism checker that scans the given text with millions of online sources to find any traces of copied text. 

So, after checking for plagiarism in the written assignment, if any plagiarism is found, students need to remove it. This can be done in multiple ways like rewriting plagiarized text in different words and quoting the copied text. Not only this, but they can also try citing the original source or using a plagiarism remover that will automatically remove plagiarism by changing words and altering the sentence structure of the given text. 

3. Take care of grammatical errors

Lastly, students also need to ensure that the written assignment is free from all kinds of grammatical errors. Submitting assignments without correction of grammar, spelling or punctuation will damage its overall quality. And all the efforts the students have spent on properly following the steps mentioned above will be in vain.

Therefore, it is essential to always check the written assignment for grammar issues. This can either be done by reading the assignment word-by-word to find errors. Although, this will not take a lot of time and effort, but also increases the of skipping small errors. Another quick way to take care of grammatical errors is by utilizing a grammar check tool.

Wrapping up

Writing incredible assignments is highly beneficial for academic students. this is so because it not only helps them to get good grades but also develops useful skills in them. However, writing high-quality is not a cup of tea, instead requires following a proper approach. This article has explained a step-by-step guide that helps students come up with incredible assignments.

In the modern era, the construction industry stands as a testament to human ingenuity and the relentless drive to build and innovate. From towering skyscrapers to intricate transportation networks, our built environment is a reflection of progress. However, this progress comes at a cost. Every construction project, regardless of its scale, generates waste. If not managed properly, this waste can have significant environmental, economic, and social implications.

The construction industry is one of the largest waste producers globally, with millions of tons of waste generated annually. This waste ranges from concrete rubble and metal scraps to insulation and packaging materials. While some of these materials are recycled or repurposed, a significant portion ends up in landfills, contributing to environmental degradation and resource depletion.

In this article, we will delve deep into the world of construction waste, exploring its types, impacts, and the engineering solutions that can transform waste from a challenge into an opportunity.

Unraveling the Layers: Understanding Different Types of Construction Waste

The construction site is a bustling hub of activity, with materials flowing in and out, and amidst this flurry, waste is inevitably generated. But what exactly constitutes construction waste? Let's break it down.

Defining Construction Waste

At its core, construction waste refers to the materials that are discarded during the construction, renovation, or demolition of structures such as buildings, bridges, and roads. These materials can be the byproduct of site preparation, excavation, or the actual building process. They might be items that are no longer needed, off-cuts, or materials that are not up to the required standards or specifications.

Classifying Construction Waste

Broadly speaking, construction waste can be categorized into two main types:

1. Hazardous Waste: These are materials that can pose a risk to human health or the environment. This category includes items like asbestos, paint solvents, and certain types of insulation.

2. Non-Hazardous Waste: This encompasses the majority of construction waste and includes non-toxic materials like concrete, wood, metals, and more.

Zooming in on Common Construction Waste Materials

• Concrete: Often the backbone of construction, concrete waste is generated from broken concrete slabs, outdated structures, or excess mixed concrete. With proper processing, it can be crushed and recycled as aggregate for new projects.

• Wood: Whether it's from off-cuts, damaged materials, or old timber structures, wood waste is a common sight. Depending on its condition, it can be recycled into chipboard, used in biomass energy, or repurposed in various ways.

• Metals: Scraps of steel, aluminum, copper, and other metals can accumulate on construction sites. These materials are highly recyclable and can be melted down and reformed into new products.

• Insulation: Off-cuts or outdated insulation materials can be a source of waste. While some insulation types can be challenging to recycle, innovations are emerging to repurpose these materials.

Hi readers! I hope are doing well and searching something thrilling. Do you ever think AutoCAD becomes reality? From a sketch of a high-rise structure to the machine design, AutoCAD is truly where creative design ideas turn into reality. For today we will discuss AutoCAD.

AutoCAD, a creative design software created by Autodesk, is designed primarily for use in architecture, engineering, construction, and manufacturing sectors. AutoCAD has changed the way technical drawings are created. From 1982, it has emphasized methods that were fast and effective rather than traditional hand-drawn ones. Overall, it is now essential in the world of designing because it can be adapted easily and is very accurate. 

The program AutoCAD includes many objects such as lines, shapes, dimensions, hatching, layers and blocks which can be reused. 3D models can be made in AutoCAD and different colors and textures can be applied to them. You can work easily in VS Code, since it offers a ribbon toolbar, an instant access command line and customizable palettes. 

Also, the software stores files as DWG and DXF, so they can be easily exchanged and opened by various design applications. Because of cloud support and mobile devices, team members can work from anywhere and at the same time. 

As technology grows, so will AutoCAD, with intelligent capabilities such as automation, cloud tools, and artificial intelligence. AutoCAD, for making building plans, circuits, or parts for machines, serves as a fast, accurate, and smart design tool.

Here, you will find the evolution of AutoCAD, its features, AutoCAD interference, skills, applications, and advantages. Let’s start.

The History of AutoCAD:

Early Beginnings:

• AutoCAD first came out in December 1982 as a desktop program for execution on microcomputers based on internal graphics controllers.

• It was one of the first CAD software programs to come into use on personal computers and thus was a revolutionary invention for designers and engineers working previously either with hand drafting or costly mainframe CAD systems..

Growth and Innovation:

• During the 1980s and 1990s, AutoCAD was made available from time to time by Autodesk to refine drawing skills, accuracy, and functionality.

• New features were introduced in the form of layers, blocks, hatching, and external references, or Xrefs.

• Windows-based operating systems offered better ease of use through graphical user interfaces.

21st Century Developments:

• At the beginning of the 2000s, AutoCAD was upgraded with functions for 3D models, rendering, and visualization.

• Autodesk introduced software for architects, electricians, and mechanical engineers known as AutoCAD Architecture, AutoCAD Electrical, and AutoCAD Mechanical.

• Using the cloud, mobile applications, and a subscription plan made it possible for everyone to team up and work on files across many devices.

Features in AutoCAD:

2D Drafting Tools:

Both new and more advanced CAD users can draw detailed technical drawings precisely with AutoCAD’s 2D drafting tools. The essential drawing tools are lines, polylines, arcs, circles, and ellipses. You can edit your drawing using trim, extend, fillet, chamfer, or array tools. The users can snap to a precise location, use object tracking, and use grid and ortho modes to achieve precision. These are required in building design, electrical diagrams, mechanical components, and civil structures design.

3D Modeling and Visualization:

With AutoCAD, you can create 3D models using solid, surface, and mesh techniques. Designers can build 3D objects from the real world, apply materials like wood, metal, or glass, and replicate lighting to produce lifelike images. This function makes product and architecture design more useful since it allows stakeholders to see the result before anything is made or built. AutoCAD also has 3D navigation tools such as orbit, viewcube, and walkthrough to study models from various aspects. The workflow of 3D modeling is mentioned below in the image.

Annotation and Dimensioning:

Effective communication is achieved through annotations such as text, multileaders, dimensions, and tables. AutoCAD supports dynamic text styles, dimension styles, and multiline annotations that automatically size. Associative dimensions automatically update when the geometry changes. All aspects of the design are therefore properly documented and ready for fabrication or construction.

Layer Management:

Layers form an important part of AutoCAD drawing organization. Layers may be assigned certain properties such as color, line weight, and line type. This comes in handy when differentiating such elements as walls, pipes, and electrical wiring within a building plan. Layers can be locked, hidden, or isolated so they can be edited freely. Layer filters and states allow for effective management of very complex drawings with many objects.

Blocks and Reusability:

AutoCAD permits the definition of predefined, reusable items such as doors, windows, bolts, symbols, or logos. Blocks enhance efficiency in drawing and guarantee consistency among projects. The user can also define dynamic blocks that resize, rotate, or reconfigure according to defined parameters. This reuse saves time while drawing and enhances standardization.

External References (Xrefs):

External references allow users to bring in other DWG files or images into the present drawing. This is useful for collaborative projects where various team members work on diverse sections, including big architectural or infrastructure projects. Xrefs will hold a live link, so any change to the reference file will be updated automatically. This will encourage collaborative working without modifying the master file directly.

Parametric Constraints:

Parametric constraints allow the establishment of relationships among drawing objects. Geometric constraints govern the shape and orientation, and dimensional constraints govern the size and distance. A designer can, for instance, ensure that two lines are always perpendicular or ensure that a rectangle always has equal opposite sides. This keeps design integrity intact in case of modifications.

File Compatibility and Formats:

AutoCAD accommodates industry-standard formats like DWG (native), DXF (for interoperability), and PDF (for sharing). AutoCAD also accommodates support for DGN (employed by MicroStation) and image formats including JPG and PNG. The feature of exporting and importing numerous file types guarantees communication across various software environments and project stakeholders without any hiccups.

Cloud and Mobile Access:

AutoCAD integration with cloud storage allows the storage of drawings directly to services such as Autodesk Drive, Google Drive, Dropbox, and OneDrive. The AutoCAD web and mobile app make it possible to view, edit, and mark up drawings from any device connected to the internet. This is particularly convenient for professionals operating on-site, in meetings with clients, or remotely.
