Good morning,
I use a push button...
I'd like if we press the first the millis() counter starts.
If I press a second time reset millis ( millis() counter becomes = 0 )
If I press it a third time, millis() starts again over from 0;
Wiring in attachment.
Thank you very much.
// this constant won't change:
const int buttonPin = 2; // the pin that the pushbutton is attached to
const int doorAPin = 3; // the pin that the pushbutton is attached to
const int doorBPin = 4; //

const int ledPindoorA = 8; //
const int ledPindoorB = 9; //
