Hello all!
I am building an LED blacklight bar (approximately 48 20mA LED's, powered by a DC transformer that I found that is 9V with a max output of 800 mA).
So far, I have the schematic for having it just turn on and off, but I would like to have a setting where I can also make it strobe (all LED's on and all off). Does anyone have any advice for how to make all of the LED's turn on and off at an adjustable rate?
Preferably, just using hardware that I can find at RadioShack (Logic gates? because I don't know how to program small chips)
Thanks a lot!
