You need a counter that counts up, counts down, and resets to a specific value without burning through a whole microcontroller. The 4516 is a pre-set up/down counter in a 16-pin DIP. Set your start value, pick your direction, clock it. CMOS keeps the standby draw negligible when the circuit's idle. Jaycar part ZC4516. $5. Add to cart and wire up your counting logic
