LED Power supply? Answered
I have approx 200 flashing LED circut boards that I want to make a twinkling display from. Each board has a single LED that flashes about every second, each board also has a single 3v cr2032 lithium battery powering it. What Id like to do is remove the battery on each one and wire them to a DC power supply that can be plugged into 120VAC. So I actually have two questions:
Should I wire these in series? Or parallel?
What size power supply would I need?
Heres a link to a picture of what I have.
Thanks (in advance) for all your help!
