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:
| Where To Buy? | ||||
|---|---|---|---|---|
| No. | Components | Distributor | Link To Buy | |
| 1 | Battery 12V | Amazon | Buy Now | |
| 2 | Resistor | Amazon | Buy Now | |
| 3 | LCD 16x2 | Amazon | Buy Now | |
| 4 | LCD 20x4 | Amazon | Buy Now | |
| 5 | PIR Sensor | Amazon | Buy Now | |
| 6 | Arduino Uno | Amazon | Buy Now | |
Let's have a look at the pinout of LCD:
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:
Serial |
Pin |
Functionality |
Description |
1 |
VSS |
Ground |
This pin is connected to the ground terminal of the circuit. |
2 |
VDD |
Power Supply |
It is connected to the positive voltage(+5V) and is responsible for the power supply to all pins. |
3 |
VEE |
Voltage Emitter |
It is used to control the contrast of LCD. it applies the negative voltage and thus controls the electric field of the LCD. |
4 |
RS |
Register Select |
It selects the LCD register. LCD has two registers: an instruction register and a data register. |
5 |
RW |
Read or write |
The read-and-write operation is done through this pin. if set to HIGH then LCD is in reading mode and LOW means it is writing the data. |
6 |
E |
Enable |
Enables the working of LCD. If HIGH then allow the display and if LOW then disable it. |
7-14 |
D0-D7 |
Data bits (Pins to deal with the data) |
Data is sent to the LCD in a parallel manner. These pins send this data and out of these, D0 is the least significant and D7 is the most significant. |
The installation of the LCD V2.0 is simple. The first step is to download the library files. I believe you have Proteus installed. So, click the below button to download the Proteus Library zip file.
The zip file also contains the project, where we simply connected both the LCDs with Arduino, so that you could check their working. Moreover, code is also present in the file.
Once the Library is installed, you need to open your Proteus software. If it's already open, you have to restart it. Now follow the instructions.
I have installed both versions therefore, I am getting four options. I will choose the LCD 20X4 V2.0 and LCD 16X2 V2.0.
Click on the components and simply place them on the working sheet of Proteus, it will appear as shown below:
Now, let's design an LCD simulation in Proteus:
Now, let's design a simple LCD simulation, where we will interface it with an Arduino UNO board. We will display our website's link on the LCD. So, let's design the circuit:
Go to the pick library and select the following components:
Now let's design the Arduino code to display data on these LCDs:
Now, open your Arduino software, I hope you have it installed. Paste the below code in it, I have also added this code in the zip file.
#include
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(13, 12, 11, 10, 9, 8);
void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// Print a message to the LCD.
lcd.setCursor(1,0);
lcd.print("www.TheEngineering");
lcd.setCursor(4,1);
lcd.print("Projects.com");
}
void loop() {
}
The next step is to get the Hex File from Arduino IDE and add in the Proteus. For this, follow these steps:
If you have followed all the steps, I am sure your project will run successfully. I hope it was helpful to you. You must practice it more and try to make different projects. So, that was all for today, will meet you guys in the next tutorial. Take care!!!
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.
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.
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.
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.
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.
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
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.
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.
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.
Apart from the steps mentioned above, there are also some useful tips that academic students need to consider to write good assignments.
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.
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.
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.
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.
