Indicator

Status lamp

For NO and COM ports, when relay is connected, LED lamp will be ON; when relay is disconnected, LED lamp will be off.

 

DEMO

Connect S port of electronic brick of relay to D2 port of Arduino board, then connect COM and NO ports of relay in series to loop of LED, and we will use the following program to make LED lamp flash at intervals of 1s.

void loop() {
  digitalWrite(relay, HIGH);   // turn the relay on(HIGH is the voltage level)
  delay(1000);               // wait for a second
  digitalWrite(relay, LOW);    // turn the relay on by making the voltage LOW
  delay(1000);               // wait for a second
