Introduction

keyestudio Relay Shield employs high quality relay with four channels input and output.

It can be connected to 250V/10A AC element or 24V/10A DC element to the maximum, therefore, it can be used to control lights, motors, etc.

The modularized design makes it easy to connect to Arduino expansion board.

The output state of the relay is shown by a LED for the convenience of actual application.

Sample Code

int BASE = 2 ;  // I/O pin connected to the first relay
int NUM = 4;    //total number of all relays
void setup(){
  for (int i = BASE; i < BASE + NUM; i ++) {
    pinMode(i, OUTPUT);   //set digital I/O pin as output
  }
}
void loop() {
  for (int i = BASE; i < BASE + NUM; i ++) {
    digitalWrite(i, LOW);    //set digital I/O pin as ‘low’, i.e. turning off the relay gradually  
 delay(200);                 //delay
  }
  for (int i = BASE; i < BASE + NUM; i ++) {
    digitalWrite(i, HIGH);    // set digital I/O pin as ‘high’, i.e. turning on the relay gradually    
    delay(200);               //delay
  }
