Hi:
1 second LED lights automatically switch off for , an example of how to write?
@ison Your question is not clear, could you write a bit more descriptive? if i understood true you can do this with this example.
const int button = D0; // the number of the pushbutton pin
const int led = D0; // 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(led, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(button, INPUT);
}
void loop(){
// read the state of the pushbutton value:
buttonState = digitalRead(button);
// check if the pushbutton is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == HIGH) {
// turn LED on:
digitalWrite(led, HIGH);
}
else {
// turn LED off:
digitalWrite(led, LOW);
}
}
How to write is correct?
Hi @ison - it looks like you’ve got the button and the LED attached to the same pin. You’ll need to put them on two different pins. Other than that, i think your code will work.
I wanted to via Tinker app just do and LED opens and automatically closes.
