Leds & Buttons

Using Arduino Project Guidance
1

Hi! I show you part of a little project I'm doing, in which when you press a button, a Led lights up:

int Led = 1;
int But = 10;
int val = 0;
void setup() {
pinMode(But, INPUT);
pinMode(Led, OUTPUT);
}
void loop(){
val = digitalRead(But);

  • if (val == HIGH) { *
  • digitalWrite(Led, HIGH);*
  • } else {*
  • digitalWrite(Led, LOW);*
  • }*

I want to make when you push the button once, the led remain shining for a while, and I tried:

val = digitalRead(But);

  • if (val == HIGH) { *
  • digitalWrite(Led, HIGH);*
  • delay(500);*
  • } else {*
  • digitalWrite(Led, LOW);*
  • }*

but it doesn't rules.... any suggestion?

Thanks!

That delay is 1/2 second. Try delay(5000);
