Reply to "Photocell tied to Start clock?"

A photocell works in a similar fashion to touching two wires together or pushing a button. Timers operate on a normally open circuit that closes when the photocell, button, wire touch occurs.

It would depend on the circuitry and programming of your start clock. Is it like a "running race" display with a countdown repeat program?

We normally use this start clock for your application. It is set up to do what you want.
