IoT-Bus Relay Example

It is very easy to use the IoT-Bus relay. Simply set the relay pin high to turn on the relay as the relay is active high. The full example is shown below.

Turns the Relay on for one second, then off for one second, repeatedly.
This example code is in the public domain.

#include <arduino.h>

#define RelayPin 17

// the setup function runs once when you press reset or power the board
void setup() {
    // initialize digital pin Relay_BUILTIN as an output.
    pinMode(RelayPin, OUTPUT);
    Serial.println("Hello world");

// the loop function runs over and over again forever
void loop() {
    digitalWrite(RelayPin, HIGH);   // turn the Relay on (HIGH is the voltage level)
    delay(1000);                       // wait for a second
    digitalWrite(RelayPin, LOW);    // turn the Relay off by making the voltage LOW
    delay(1000);                       // wait for a second
