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 […]

Arduino Pure Sine Wave Inverter Circuit with Full Program Code
This article explains a simple pure sine wave inverter circuit using Arduino, which could be upgraded to achieve any desired power output as per the user’s preference. Circuit Operation In the last article I have explained how to generate sine wave pulse width modulation or SPWM though Arduino, we are going to use the same […]
Real MPPT Solar Charger Circuit Using Arduino, LCD, and Manual/Auto Switch
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 […]
Arduino Automatic School/College Bell System
In this post I will show how to construct an automatic school bell/college bell system using Arduino, 16 x 2 display and real time clock module. You can program this project to ring the bell up to 16 times a day at your preferred hour and minute. The length of the bell ring can be […]
How to Make TDCS Brain stimulator Circuit
In this article I will show how to construct an interesting project, which could potentially enhance your brain’s capability. I have explained how to make a TDCS brain stimulator circuit. Overview This may sound like science fiction, where an evil scientist connects his head to some complex machine and gaining super human capabilities. This may […]
2.4 GHz 10 Channel Remote Control Switch Circuit
In this post I will show how to construct a 10 channel remote control switch circuit based on ISM (industrial, Scientific and Medical) band. Introduction The ISM band is operated at 2.4 GHz, which can be used without licensing with reasonable power output. The proposed project is general purpose ON/OFF wireless switch, which can be […]
