    Simple project: Escape room switch locks.

    A customer of mine manages a few Escape rooms in Ljubljana, so he occasionally asks me to develop a problem for him.

    Recently he needed two simple locks, preferably electronic and they have to be one red, the other blue.

    So, I proposed two simple solutions, no programming needed, because that would have made the lock much more expensive.

    Any problems with the LED blowing from inductive kickback?

    Personally I'd either use an AC LED or put a verse biased diode across the LED. I might even put a small capacitor across the LED to slow down the dV/dT from the coil.

    Good question.

    No, no burnt LEDs yet.
