Ive searched the internet and checked some old circuit books around but I cant seem to find a circuit to do what I want. Basically it needs to:
- Set a 7-seg display to show up 10 when powered on
- Count down from 10 when a certain switch is closed/pressed
- When the timer hits zero, the display stays at zero and fires a one-shot
- This one-shot triggers a relay on and off, preferably with it on only for about 1-2 seconds
