In this quick Arduino ... Relay = 2; int stateRelay = LOW; int stateButton; int previous = LOW; long time = 0; long debounce = 500; int stayON = 5000; //stay on for 5000 ms void setup() { ...

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino ... In the setup() function we set all led pins as OUTPUT using a for loop. I won’t insist on how the for() loop ...
