i thought of doing this with a pic chip and a tactile button on the back
have the pic programmed to act as a on off switch with the push of the tactile and you could also program different flashing mode's into it. or something like that.
only thing is im not a coder so cant right the code for it myself
if any1 can that'll be cool
have so it can run like 5 seterate led's or 5 sets of leds, and a tactile push button for mode changing.
