SIMPLY RELAY AND ARDUINO PROJECT

Arduino Based Relay project 

WHAT YOU NEED:

1) A Realy Module (IM USING KEYES)

2) 9V Battery

3) 9V Battery Connector
4) 2 Jumper wire and wires

5) A 9V LAMP

Connection

Code-

int Relay = 7;
int stateRelay = LOW;
;
 
void setup() {

  pinMode(Relay, OUTPUT);
}
 
void loop() {
 digitalWrite(Relay,LOW); // Turns ON Relays 1

Serial.println("Light ON");

delay(2000); // Wait 2 seconds

digitalWrite(Relay,HIGH); // Turns Relay Off

Serial.println("Light OFF");

delay(2000);
}
