Inverter is a useful device in electronics. It changes DC (Direct Current) to AC (Alternating Current). In this project for Arduino Based Power Inverter Circuit we will make simple inverter using Arduino. It takes 12V DC and gives 230V AC. We have used Arduino UNO, IC 7809, some transistors and a reverse transformer to get […]

In this post for Simple Flame Sensor Circuit using Arduino shows how to connect flame sensor to Arduino to find fire. This project is cheap and works well for real-life fire detection. Coding: Code for Flame Sensor Digital (D0) […]
Simple Arduino Based Electromagnetic Field Detector Circuit
EMFs (electromagnetic fields) are invisible energy from electricity and lights which are natural and man made. Some EMFs are safe and some are bad if used too much for long time. We can use simple Arduino tool to find EMFs around us. Moving electric charge make EMFs. EMFs have two parts: electric field and magnetic […]
