Introduction

The Relay Module is a digital normally-open switch. Through it, you can control circuit of high voltage with low voltage, say 3V on the controller. There is an indicator LED on the board, which will light up when the controlled terminals get closed. The peak voltage capability is 250V at 10 amps.The Module Operating Voltage 3.3V, max 3.6V .

Simple Code

/*
  LinkNode Relay-1Channel
  the Relay will turn on for 0.5s and then turn off for 0.5s, and so on.
  This example code is in the public domain.
 */
 
int RelayControlPin = 2;
void setup() {                
  // initialize the digital pin as an output.
  pinMode(RelayControlPin, OUTPUT);     
}
 
void loop() {
  digitalWrite(RelayControlPin, HIGH);   // set the relay on
  delay(500);              // wait for a second
  digitalWrite(RelayControlPin, LOW);    // set the relay off
  delay(500);              // wait for a second
}
