Description

Tutorial : Interfacing the relay modules to the Arduino (Module Relais 4 canaux 5V Arduino)


To connect the 4 Relay board to an Arduino is very easy and allows you to turn on and off an wide range of devices, both AC and DC. The first to connections are the ground and power pins,  You need to connect the Arduino +5v to the 4 Relay board VCC pin and the Arduino ground to the 4 Relay board GND pin.  Then it’s a only a matter of just connecting the communication pins, labeled IN1, IN2, IN3 and IN4, two 4 data pins on the Arduino.In the example code below we used Arduino pins 7, 8 , 9, 10.  Its a good idea to avoid using Data pins 0 and 1 as they are used by the Arduino for serial communication and can cause problems when uploading code to the Arduino.

The default state of the relay when the power is off for COMM (power) to be connected to NC (normally closed), this is the equivalent of setting the 4 Relay boards IN pin to HIGH (has +5v sent to it)  It is a safety feature to not use the NC connector in-case you Arduino looses power it will automatically turns off all the devices connected to the relay.  When you have something connected to the relays NO (Normally Open) connector and you set the corresponding IN pin to LOW (0v), power will flow in from the COMM connector and out of the NO connect or powering your device..

 // Basic 4 Realy board connection

// Each relay is turned on for 2 seconds and then off.

// You can here them click as there state changes from off to on and on to

// off.

// You will also see the corresponding Red LED on the 4 Relay board

// light up when the relay is on.

 

 //  define names for the 4 Digital pins On the Arduino   

 

// These data pins link to 4 Relay board pins IN1, IN2, IN3,
