Need Help with Bipolar LED's and minimal digital pins
hi,
in photo below have drawn ruff diagram of idea use bi polar led's. using 8 led's , don't have 16 pins both blue , yellow pins led (blue , yellow bipolar colours led). trying accomplish can control 8 led's separately , choose switch of them blue yellow if wish using total of 10 pins (8 led's , 2 switching between either blue or yellow).
the voltage in 9.6v , splits 8 led's (in diagram didn't show 8 because have same circuitry). pins 3-10 control led's, on/off state. after pins 1 , 2 attached led's (pin 1= blue pin 2= yellow).
so asking work or not , maybe suggestions appreciated.
note: schematic doesn't show 2 legs blue , yellow on led, imagine their.
thanks, ken

why don't take time , document propose instead of asking rest imagined, or implied, or assumed?
