Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to elaborate about the Introduction to LM324. It is an Operational Amplifier (Op-amp) consists of four channels. Its a low cost device having true differential inputs.For single supply applications LM 324 are superior to the other operational amplifiers. LM-324 is capable of operating at the minimum voltage up to 3V and at the high voltage levels up to 32V.
One of the major advantage of LM-324 is that common mode input range includes negative supply which eliminates the need of external biasing. Negative power supply voltage is also included in output voltage range. This device is lead (Pb) free, halogen free and RoHS compliant. It consists of four amplifier ...
Hello friends, hope you all are having fun and enjoying life. Today's post is quite a simple one and is about designing of circuit diagram of buzzer in Proteus ISIS. Buzzer is quite a common electrical component which is used in almost every Embedded Systems project. For example, you have seen a simple UPS, it gives a beep each time the light goes off or it has depleted its battery. Buzzer is normally used for given some indication and normally this indication is kind of a warning.
Proteus has a builtin component for buzzer and its an animated component means it gives a sound (beep) when its turned ON. So, I am gonna use that one and will give you an actual beep on it. So, it won't be much difficult and quite a simple procedure. In this post, I am ...

Hey Pals! We hope you are doing Great. Today, we are going to design another application of DLD Logical Gates i.e. Half Subtractor. In our previous lectures, we covered Adders in detail, where we studied both Half Adders & Full Adders. Now its time to discuss its reciprocal i.e. Subtractors.
In this session, we'll seek the answers to the following topics:
What is Half Subtractor?
Working Principle of Half Subtractor.
Truth-table of Half Subtractor.
Simulation of Half Subtractor in Proteus using three Logic Gates.
Designing of Half Subtractor with NOR gate.
So, let's get started:
What is Subtractor?The functionality of Subtractors is exactly the opposite of Adders(we discussed in previous lectures) and defined as:A Subtractor is a simple DLD Electronic circuit, d ...
Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge with all of you guys about how to do the DC Motor Direction Control in Matlab using serial communication with Arduino UNO. Serial communication is a very common and fast mean of communication now a days. In almost every engineering related projects we need to continuously send and receive data from micro controller to the computer and vice versa. So, I used this type of communication between Matlab and Arduino UNO. You must have a look at my previous tutorial DC Motor Direction Control using Arduino because I am gonna use the same hardware and Arduino code and in today's tutorial I am gonna interface that hardware project with MATLAB so it ...
ESP32 module comes with multiple inbuilt features and peripheral interfacing capability is one of those features. ESP32 module also consists of an inbuilt temperature sensor, but that can only measure the temperature of the ESP32 core not the temperature of the surrounding environment. So it is required to use a peripheral sensor to measure the temperature of the surrounding environment like home, garden, office etc.
Hello readers. I hope you all are doing great. In this tutorial, we will learn how to interface DHT11 (temperature and humidity sensor) with the ESP32. Later in this tutorial, we will discuss how to share the sensor readings obtained from the DHT11 sensor to a web server.
Before moving towards the interfacing and programming part, let’s have a short introduction to the DHT11 ...
Hi Guys! Hope you’re well today. I welcome you on board. In this post, I’ll walk you through How to Install PCBWay Plugin for FreeCAD PCB Software.
Before we move further and help you with the installation of the plugin, let’s get a brief introduction to the FreeCAD software.
FreeCAD is a free and open-source parametric 3D modeler used to design real-life objects. With parametric modeling, you can easily modify your design and change its parameters. The tool is mainly used in mechanical engineering for product design and also proves to be handy in electrical engineering for electronic board designs. It supports Windows, Linux and macOS operating systems. Python programming language is primarily used to extend the overall functioning of the software.
Hope you’ve got an ...
Hello friends,I hope you all are fine and having fun with your lives. In today's tutorial, I am going to share a new Proteus Library named as Flex Sensor Library for Proteus. I am quite excited while sharing this one because we are the first one to design this library and share it online. Although, I wanna add one thing here that most of the flex sensors are analog sensors and their resistance changes over bending and believe me I have tried my best to design an analog sensor but despite the efforts we couldn't so I am sharing a digital version of Flex Sensor. So, its not gonna detect how much its bent but it will detect whether its up or bent. So, I thought to share it with you guys. It's better to have something than nothing. You should also have ...
Hey readers! Hopefully, you are having a great day. Today, we will discuss Laser Direct Imaging (LDI) and its role in PCB fabrication. Laser Direct Imaging (LDI) is a computer-directed method that employs laser beams to expose circuit patterns directly onto photoresist-coated PCBs, without the need for conventional photomasks.
Printed Circuit Boards are the unobtrusive facilitators of contemporary technology, energizing anything from consumer products to aerospace technologies. As the pace of technology advances, however, the electronics within must make their circuits tighter, more advanced, and more efficient. Complying with these demands depends on innovation along every production process, particularly with how circuitry patterns are replicated onto the board.
This important step, im ...
Hello friends, I hope you all are doing great. Today, we will create a web server with ESP8266 microcontroller to control the activation of an LED. The goal is to understand how the ESP8266 connects to a WiFi network, how it sets up a web server, and how it is possible to exchange information between the browser and the esp8266.
Components Required
1x Computer/notebook with Arduino
1x Mini-USB cable.
1x NodeMCU (ESP8266 Breakout Board)
Internet Browser (Chrome, Firefox, IE…)
ESP8266 Libraries for Arduino IDE
For this project, we will use two libraries:
ESP8266WiFi: This library carries all the functions necessary for the ESP8266 to connect to a wifi network.
ESPAsyncWebServer: This library carries the functions needed to create an ...
