Tell us about yourself!
Have been looking some more on this, and i am still confused. Why do you use multiplexers for 16 pots on a mega (which already have 16 analog inputs)?If you actually use the Uno and shown in the pictures i understand. But your componentlist say mega.
Really difficult to understand this instruction. It uses a mega, but your pictures show an uno, and the real schematic which SHOULD be easy to understand, even me with electronics background don't really understand it. I hate looking at videos for soldering and stuff, so i thought i would try the schematic, but it is uncomplete regarding the resistor values. R2 and R3 ?? they are marked, but where are they?
