This project demonstrates how to interface a relay module with an Arduino to control high-voltage appliances safely. The setup involves using a relay as a switch, allowing the Arduino to control ...

A single-channel relay is an electronic switch that can be controlled by a low-power electrical signal, such as the output from an Arduino microcontroller. By using an Arduino Uno and a single-channel ...

This week I explore how to use the Arduino to drive lights and motors, and take over the world, with a few lines of code and a handful of electronics.

Arduino firmware for a computer interface for up to three latching relays. - kpreid/relay-controller ...
