Hello !!
I tried to detect when a light is On and write on the serial port, but I don't find how.
Maybe someone can help me ? I just begin
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.This example code is in the public domain.
*/// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int derniere = 0;
int led = 13;// the setup routine runs once when you press reset:
void setup() {Serial.begin(9600);
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a secondif ( derniere == HIGH){
Serial.print("The Lamp is ON ");
Serial.println("The Lamp is ON ");
