Hello friends, I hope you all are fine and having fun with your lives. Today, I am going to share a new project which is Receive SMS with Sim900 & PIC Microcontroller using AT Commands. I have already posted this same project on Arduino named as Receive SMS with AT Commands using Sim900 & Arduino. In that project, I have interfaced SIM900 module with Arduino but today I am gonna interface it with PIC Microcontroller.
I have also designed a GSM Library for Proteus using which you can easily now simulate your SIM900D module in Proteus. Sim900 Module is used to send and receive SMS and it is widely used in automation and security projects. I have also posted another Project in which I have designed the Proteus simulation of GSM based Home Sec ...
Hello learners, Welcome to another tutorial on signals and systems. We are learning about the responses of the signals. We all have experience in situations where the change in the frequency of a system, such as radios or control systems, results in a change in the working or result of that system. So we have the idea that frequencies play an important role in different types of systems. In the previous lecture, we saw the impulse response of the system. Our mission today is to learn about the frequency response of the LTI system. We will learn all the basic information about the topic and will revise some important points as well. To do this, have a look at today’s concepts:
What is the LTI system?
What is frequency response?
How is frequency response performed without the function i ...
Hello readers, I hope you all are having fun in your lives. Welcome to the 2nd Chapter of Section-2 in the ESP32 Programming Series. In today's lesson, we'll go over another built-in feature of the esp32 module that helps it stand out from the competition: BLE or Bluetooth Low Energy. In the previous tutorial, we discussed the Classic Bluetooth in ESP32, which is considered the predecessor of Bluetooth Low Energy(which we are going to discuss today). We will first look at, what is BLE? and why is it used?, and then will design some examples to utilize the ESP32 BLE in Arduino IDE.
What is BLE?
There have been numerous adjustments and upgrades to Bluetooth's characteristics since its inception, where Bluetooth 4.0(also called BLE or Bluetooth Smart) is the most influential.
B ...
Hello, my friends and welcome back with one new tutorial of our ladder logic programming series. Today I am bringing one exciting project which you can see everywhere, in your home, work, and public places, which is an elevator. We will design a solution using plc ladder logic programming, which drives the elevator. Our elevator is composed of 4 floors and has all capabilities of large-scale elevators. So let’s get started and save time and jump into our tutorial.
Elevator Project
As you can see, Everyone figure 1 depicts the complete scene of the project and tells that the elevator we will manage has four floors to visit. On the first floor, there is only one outer request to call the car from any floor above, i.e. from floor 2, floor 3, or floor 4. While on the second floor, there are ...
Hello everyone, I hope you all are doing great. In today's tutorial, we will have a look at the Air Conditioning revolution brought by HVAC. Air conditioning is a mainstream engineering wonder, and much of the world relies on their HVAC for comfort and day-to-day living. Unfortunately, as a study in the Journal of Energy and Buildings found, HVAC systems come with a high environmental cost amounting to 40% of energy consumption in all residential sectors. This comes chiefly from heat transfer, but also from air cleaning processes and lost energy. Clearly, huge efficiencies need to be found in the HVAC/air conditioning sector – and innovation is providing.
The air we breathe
A large component of the inefficiency of HVAC is through the air filtration ...
Selling an app to a buyer requires a careful approach to extract the most value from the digital asset. The marketplace for apps extends well beyond the iOS and Android market to ones for e-commerce platforms, Amazon’s Alexa, Salesforce, and many other places.
If you’re thinking ahead about the long-term prospect of selling your app that’s now in development or wanting to exit in the next year, these 5 tips for selling an app are for you.
Can You Sell The App?
You might believe it is time to cash out your app, but there could be a few problems in your immediate future. Apps developed for the Apple ecosystem can’t always be transferred from one developer to another. It is a good idea to check the latest criteria on app transfers before you look at ...
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, contribut ...
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 D ...
Hello friends, hope you all are fine and having fun with your lives. In today's post, I am gonna design a Convolution Calculator in MATLAB. We all know about convolution but if you don't know then here's the wiki page for convolution which has a detailed description of Convolution. In simple words, convolution is a mathematical operation, which applies on two values say f and g and gives a third value as an output say v. In convolution, we do point to point multiplication of input functions and gets our output function.
Convolution is an important technique and is used in many simulating projects. It has a vital importance in image processing. So, today we are gonna do convolution in MATLAB and will check the output. You should also check Image Zo ...
Hello friends, hope you all are fine and having fun with your lives. In today's post we will have a look at How to interface keypad with Arduino in Proteus ISIS. Keypad is used almost in every engineering project. If you even look around you will find keypad in many electronic appliances. For example, a simple ATM machine has a keypad on it using which enter our pin code and give commands to the ATM machine. Similarly, calculator also has keypad on it. So, in short there are numerous applications of keypad. You should also read the Real Life examples of Embedded Systems and you will find Keypad in them as well.
Keypad is used where you need to used numerical buttons or you need to use lots of buttons for sending commands so like in some applicatio ...
