Colourfade Mod

Not open for further replies.


there is a schematic on this site and was wondering if it was possible to add more than the two different colours that are in it. I was planning on using up to five Leds if possible.

for those who for some reason cannot see the site mentioned above I will explain the theory behind the circuit. basically what it does is use a LM324 to fade between two different leds to give it a fibre optics kind of look.

now my question is is it possible to modify this circuit or use different parts so that i would be able to use more than three leds that are constantly changing colour? five or more leds would be tops.

thanks alot
