I have searched the whole dang internet and various forums, but my google-fu is letting me down. I have been thinking of building an Aquaboy, but would like it to have switching like the AnalogMan delay. If you don't know what it is, they are switching between two sets of pots with LEDs showing what set is on.
My question is: How are they doing this? And, more importantly, how can I do it with an Aquaboy?
Help me, forum members, you are my only hope
