I am just starting out with arduino and have very little skills,
I was wondering if anyone may be able to help me out on how to make a 120 hour countdown timer, with the the time remaining coming up on the standard lcd display. also the time would have to be able to be paused. (i have an UNO board)
How would you wire the project & is there a template for the code???
Your time and help wound be greatly appreciated…
