hi Arrch,
you right, but my question is where to start. The basic code is form the button example. My problem is how the same button can turn of the LED within the delay time. Sure the code "stuck" by the delay.... this will not work
i try again to explain:
I have a LED which i can turn on with a Pushbutton. The LED will be on for, lets say 10min and will then turn off automatically. Here my problem: I would like to be able to switch off with the same Pushbutton the LED within the 10min.
// constants won't change. They're used here to
// set pin numbers:
const int buttonPin = 2; // the number of the pushbutton pin
const int ledPin = 13; // the number of the LED pin
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
void setup() {
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);
}
void loop(){
// read the state of the pushbutton value:
buttonState = digitalRead(buttonPin);
// check if the pushbutton is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == HIGH) {
// turn LED on:
digitalWrite(ledPin, HIGH);
delay(100000);
}
else {
// turn LED off:
digitalWrite(ledPin, LOW);
}
}
