100A AC Load Monitoring Circuit using Arduino, Watt Limit, LCD, Alarm, Auto Shutdown

Last Updated on June 3, 2025 by Swagatam 2 Comments

In this project we are going to make one very useful grid power protection circuit. This will be like a power guard system which we can use in homes or apartments to monitor the wattage of the load and also to cut off the load automatically if it starts taking too much wattage, more than […]

Making an EGS002 Equivalent Board using Arduino

Last Updated on May 28, 2025 by Swagatam Leave a Comment

The EGS002 board is nothing but a combination of a microcontroller with a H-bridge driver like the IR2110. So if you are interested to build your own EGS002 equivalent board with exactly identical features, then you can do it using the instructions given in the following article. So, here we are trying to build our […]

Real MPPT Solar Charger Circuit Using Arduino, LCD, and Manual/Auto Switch

Last Updated on May 19, 2025 by Swagatam 4 Comments

So in this article we are trying to make a true MPPT solar charger project using Arduino which will charge a 12V battery from a solar panel and will use MPPT logic to always extract maximum power from the solar panel. That means that even when sunlight changes, we try to adjust PWM duty cycle […]

H-Bridge Sine Wave Inverter Circuit using Arduino

Last Updated on May 24, 2025 by Swagatam 30 Comments

In this article I will explain how we can build an Arduino-controlled H-Bridge sine wave inverter circuit using some easy parts. So this thing will basically convert DC into AC but in a way that looks like a sine wave, right? We are using an Arduino to generate PWM signals and these signals will drive […]

Line Follower Robot Circuit without Microcontroller or Arduino

Last Updated on March 26, 2025 by Swagatam 8 Comments

line follower diagram

In this article I have explained a simple line follower robot circuit, also known as line tracker vehicle, using just a couple of op amps from the IC LM324 and a few other components, without using complex Arduino or microcontrollers. It means this project can be built without any coding, just by using discrete components, […]

Arduino 2-Step Programmable Timer Circuit

Last Updated on December 5, 2024 by Swagatam 40 Comments

Arduino programmable timer circuit

In this article I have explained how to make a simple 2-step Arduino programmable timer circuit, which can be used to switch an electrical load ON/OFF with independently adjustable ON and OFF timings. For example if you want a light to remain ON for 24 hours and OFF for 2 hours, you can simply do […]
