Guide for Relay Module with Arduino

A relay is an electrically operated switch of mains voltage. It means that it can be turned on or off, letting the current go through or not.
Controlling a relay with the Arduino is as simple as controlling an output such as an LED.

Mains voltage connections

In relation to mains voltage, relays have 3 possible connections:

COM: common pin

NO (Normally Open): there is no contact between the common pin and the normally open pin. So, when you trigger the relay, it connects to the COM pin and supply is provided to a load

NC (Normally Closed): there is contact between the common pin and the normally closed pin. There is always connection between the COM and NC pins, even when the relay is turned off. When you trigger the relay, the circuit is opened and there is no supply provided to a load.

If you want to control a lamp for example, it is better to use a normally-open circuit, because we just want to light up the lamp occasionally.

Pin wiring

The connections between the relay module and the Arduino are really simple:

GND: goes to ground
IN1: controls the first relay (it will be connected to an Arduino digital pin)
IN2: controls the second relay (it should be connected to an Arduino digital pin if you are using this second relay. Otherwise, you don’t need to connect it)
VCC: goes to 5V
