This Automatic Battery charger circuit can be used to charge a 12V, 7Ah battery, or above. The charger maintains float voltage, if battery is fully charged.

I used an ordinary transformer (220V to 12V) and verified the output just by using this. Please check the figure-7 for the connections. I have to note that the load must be connected, otherwise you ...

This project demonstrates how to design and implement an IoT-based light dimmer and speed controller using Arduino. Users can remotely and precisely adjust both light intensity and motor ...

This Arduino lights dimmer project is based on Doug Hitchcock’s comment: “I need to have a lamp dimmer that can “cascade” from one lamp to the next (up to 4 lamps). Basically, when you close a switch, ...

Arduino software and hardware to control a 12V off-grid solar system with 1000W power inverter for a fridge and lighting. The arduino is a 3V JeeNode, but I might change it for a simple arduino.

A switch is the most essential part of any circuit. Different circuits use different switches in them. In this project, we are going to use a Touch Dimmer Switch. This switch is a touch-sensitive ...

The ESP32-based AC voltage controller can be programmed with Arduino. But for some reason, the company mentions “Arduino V2.3.4-compatible source code” and recommends using that version of the IDE, ...
