// Introduction to 5V relay.
int relayPin = 2;// define pin for relay
void setup() {
// Robojax.com relay tutorial 20181012
pinMode(relayPin, OUTPUT);
Serial.begin(9600);// initialize serial monitor
Serial.println("Robojax.com Relay Module");
digitalWrite(relayPin, HIGH);// turn relay ON
delay(2000);// wait for boot
}
void loop() {
// Robojax.com relay tutorial 20181012
digitalWrite(relayPin, HIGH);// turn relay ON
Serial.println("Relay ON");
delay(300);// wait for 5 seconds
digitalWrite(relayPin, LOW);// turn relay OFF
Serial.println("Relay OFF");
delay(1000);// wait for 3 secons
}
