Easy Remote controller Relays

Easy way to controller relays with Easy Remote and simple sketch.





Easy Remote +Arduino+Relays+Bluetooth

on app I used Raw Code Layout   Button 1 =off, Buton 2 = on

sketch.Here




/*
simple relay on/off
*/

char val;         // variable to receive data from the serial port
int ledpin = 2;  // relay connected to pin 2
void setup()
{
  pinMode(ledpin = 2, OUTPUT); // pin 2 as OUTPUT


    Serial.begin(9600);       // start serial communication at 9600bps

}

void loop()

{
  if( Serial.available() )       // if data is available to read
  {
    ;
  }
  val = Serial.read();         // read it and store it in 'val'

  if( val == '1' )               // if '1' was received led 2 is switched off
  {
    digitalWrite(ledpin = 2, LOW);    // turn Off pin 2
  }

  if( val == '2' )               // if '2' was received led 2 on
  {
    digitalWrite(ledpin = 2, HIGH);  // turn ON pin 2
  }
 
}
