Quoted from CaptainNeo:Looking for some ideas on how to wire up a switch to work when a certain light comes on.
I'm thinking of using a photocell aimed at the bulb, to trigger, but all the photocells I seem to have, either have more resistance as light is projected on it. or decrease, but not enough to become a completely closed circuit (stays 1000 ohms).
So i'm looking for ideas on how to wire something like this to activate or deactivate due to the bulb coming on or off.
I did this with a photocell and an Arduino for an attract mode program triggering off the game over light. I'll have to look and see what photocell I used.
