This is a fully customizable countdown timer model made by me, Username. Use is simple, the relay on the far left, if enabled, will reset the timer when it reaches zero. The relay on the far right is triggered every time the timer hits zero. There's a relay to start, stop, and reset the timer, along with two relays to set the tens and ones digits, respectively. All those are in the center and aptly named. This doesn't just have to be a countdown timer, either. You can use it to count down kills, caps, anything of the sort. If somebody needs it, I can convert it into a count-up timer. I'll also add additional digits upon request.
