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.begin( 115200 );
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
}
