Arduino 2 Channel Relay : 3 Steps

Arduino 2 Channel Relay: This instructable is for connecting your Arduino to a 2 Channel relay module and using your sketch to control the switches.I bought the 2 Relay Module on eBay (for $9.50) to drive a couple of 240V parts (a vacuum cleaner and a rotary engraving tool)…

Guide for Relay Module with Arduino | Random Nerd Tutorials

This module should be powered with 5V, which is appropriate to use with an Arduino. There are other relay modules that are powered using 3.3V, which is ideal for ESP32, ESP8266, and other microcontrollers. Get a relay module: 5V 2-channel relay module; 5V 1-channel relay module; 5V 8-channel relay module; 3.3V 1-channel relay module; Relay Pinout

How to Set Up a 5V Relay on the Arduino

One of the most useful things you can do with an Arduino is control higher voltage (120-240V) devices like fans, lights, heaters, and other household appliances. Since the Arduino operates at 5V it can’t control these higher voltage devices directly, but you can use a 5V relay to switch the 120-240V current and use the Arduino to control the relay.

In

In the above wiring diagram we have kept the jumper in place, due to which the electromagnet of the relay will be driven directly from the Arduino. In this case the relay module and the Arduino will not be physically isolated from each other.
