Code

Relay

Arduino
Main code to configure the Relay
/*   Relay and Arduino >>>> code by @_carlos_dev     */

int relayPin = 8;           //Assign Pin 8 to the relay control/signal pin

void setup() {
  // put your setup code here, to run once:
  pinMode(relayPin, OUTPUT);      //Setting the Relay pin as an Output Pin
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(relayPin, HIGH);        //Turn the relay ON for 1 second
  delay(1000);
  digitalWrite(relayPin,LOW);          //Turn the relay OFF for 1 second
  delay(1000);
}

Relay Tester

Arduino
To test the coil and electromagents of the relay
/*   Relay and Arduino >>>> code by @_carlos_dev     */

int relayPin = 8;                       //Assign Pin 8 to the relay control/signal pin

void setup() {
  // put your setup code here, to run once:
  pinMode(relayPin, OUTPUT);          //Setting the Relay pin as an Output Pin
}

void loop() {
  // put your main code here, to run repeatedly:
