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 ...

In this arduino relay control tutorial we will simply learn How to interface a Relay with Arduino. Here we are not using any Relay Driver IC like ULN2003 and will only use an NPN transistor to control ...

Here, we are using a 4 relay module because we will only control four appliances. If you want to automate a different number of appliances, you can use a different relay module. There are many relay ...

Relay-Interfacing-with-Arduino 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, ...
