Electronics Projects

In this project, we are going to make a TRIAC dimmer circuit for AC Appliances. Here we are not going to use a microcontroller. We have used basic components to complete this task. In this project, we will use Triac to control the brightness of the AC bulb with a IR TV Remote. You can also control Fan speed with your TV remote using this Triac Dimmer circuit.

We have limited natural resources and that too we are using in generating Electricity. That’s why there is lot of emphasis is given on generating and using clean energy. Today in this project, we will see how electricity can be generated from the sunlight, how it can be stored in the form of DC, and then how it is converted into AC to drive home appliances.

Health monitoring is the major problem in today’s world. Due to lack of proper health monitoring, patient suffer from serious health issues. There are lots of IoT devices now days to monitor the health of patient over internet. Health experts are also taking advantage of these smart devices to keep an eye on their patients. With tons of new healthcare technology start-ups,…

In the era of Internet of Things (IoT), wireless communication is getting increasingly popular in everyday life. Nowadays, devices can talk to each other over the cloud or local network. When we talk about local wireless communication, we need an RF system module that executes these tasks, we see can find various RF system modules with various configurations like Bluetooth…

NodeMCU is a low-cost open-source IoT platform that initially included firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which was based on the ESP-12 module.

If you are getting started with IoT or microcontrollers in general, this development board is a fierce competition to everything that you’ll come…

Many of us should be familiar with the popular microcontrollers and development boards like Arduino, Raspberry Pi, ESP8266, NoduMCU, 8051, etc. In fact, for most people, Arduino would have been their first development board, but as we dig deep and begin professional designs, we will soon realize the limitations of Arduino (like cost, versatility, stability, speed, etc.) and…

From the assembly line of automobile manufacturing industries to the telesurgery robots in space, Robotic Arms are to be found everywhere. The mechanisms of these robots are similar to a human which can be programmed for similar function and increased capabilities. They can be used to perform repeated actions faster and accurate than humans or can be used in harsh…

Raspberry Pi is a small or mini-computer that can be used in different types of small to large embedded, IoT, Industrial IoT applications. As this is a computer that could run different operating systems, a shutdown of this minicomputer is an important thing to ensure that everything is saved, the operating system properly ended all required tasks, and it is safe to turn the…

Since the outbreak of Covid-19, infrared thermometers are being used as a screening tool to scan the people at Airports, Railway Stations, and other crowded establishments. These scans are being used to identify potential patients of Covid-19. The government made it compulsory to scan everyone before entering the office, school, or any other crowded place.

Although there are inverters and generators to immediately start the AC power supply whenever there is a power cut but sometime when there is no backup support and we have some critical machines running to perform some important task, it’s a good idea to atleast have an alarm which notify us as soon as power goes off. In this tutorial, we will learn how to make a simple…

There are several ways to program AVR microcontrollers. We are programming it with USBASP v2.0 serial programmer. For demonstration we will use ATmega16 Microcontroller and Atmel Studio. We will test the programmer with a blink sketch.

Below are the steps to burn the code into Atmega ICs using USBASP JTAG and Atmel Studio:

Transistors are made up of semiconductor material which is most commonly used for amplification or switching purpose, although they can also be used for controlling the flow of voltage and current. Not all but most of the electronic devices contain one or more types of transistors. Some of the transistors placed individually or else generally in integrated circuits…
