EASY plug Single Relay Module



Relay is an automatic switch element with isolation function. It's widely used in remote control, remote sensing, communication, automatic control, mechatronics and electronic devices. It is one of the most important control elements. Besides, it’s easy to control and use just by inputting different level signals to corresponding ports of the relay. The single relay we introduced here has a status indicator light, convenient for you to observe the on and off status of the relay.
Note: this module needs to be used together with EASY plug control board.

Connection Diagram

Now, let’s connect this module to the D8 port of the controller board using the EASY plug cable.

Sample Code

 int Relay = 8;
  void setup()
  pinMode(Relay, OUTPUT);     //Set Pin3 as output
void loop()
  digitalWrite(Relay, HIGH);   //Turn on relay
  digitalWrite(Relay, LOW);   //Turn on relay
