Analog In only pins have no internal pullup resistors.
thus two preset switches need pulldown resistors on pcb to be soldered
and switch to 3v instead of GND
- changed in connection plan
- changed switch config in config.cpp (no pullup, inverted)
Fix manual mode:
previously there was a bugged change loop when pressing all 3 buttons
- made mode switch more clear
