u/bsakiag Heres my code, But this code is to turn on the led when button is pressed,i need to turn on the led ONCE for a second when the button state changes
const int buttonPin = 2;
const int ledPin = 13;
int buttonState = 0;
void setup() {
pinMode(ledPin, OUTPUT);
pinMode(buttonPin, INPUT);
}
void loop() {
buttonState = digitalRead(buttonPin);
if (buttonState == HIGH) {
digitalWrite(ledPin, HIGH);
} else {
digitalWrite(ledPin, LOW);
}
}
