Working Thing and not working Idea
Howdy-
so … made a Green LED turn on with one press of a button. Made an orange LED turn on when that same button was pressed twice. Made both LEDs turn off when the button was pressed a third time.
Here is a video example:
However, after this, I wanted to reset the button count to NIL if no other button presses followed. I tried to unsuccessfully attempt a “millis” into my code. Please see the comments section for that code, and any suggestions are greatly appreciated.
