All,
I'm a non-EE designer and need to show a nightlight prototype for
demonstration.
I have a single-cell AAA attached to a mini-Maglite replacement bulb
(designed for this battery size), and it is plenty bright. Of course, I
can add a manual switch.
Can anyone suggest the simplest circuit that would provide automatic on/off
based on lighting intensity? I think I need a photocell or photodiode, but
beyond that I'm clueless. Obviously it would be nice to adjust the
sensitivity using a small pot in the circuit. Also, it's desireable to
keep the AAA single-cell battery configuration if at all possible.
Hope someone can help!
Thanks,
Ed Clapper
