instead of a microcontroller i use simple reed magnet switches
the two outer rings consist of 18 Led’s in 6 groups each all is powered by two AA batteries they are located on the hub
the only thing i don’t have because i use the reed switches is the cool animation like revolights when the wheel stands still
