H-Bridge Sine Wave Inverter Circuit using Arduino

Last Updated on May 24, 2025 by Swagatam 64 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 […]

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

Last Updated on May 19, 2025 by Swagatam 13 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 […]

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, […]
