how do i drive a dual color led display with an arduino?
and here is the datasheet: http://www.sparkfun.com/datasheets/Components/SanYoung-Medium-RG.pdf
i am trying to make a simple 3 color clock (or something like that) with a dual color RG led matrix and an arduino.
can someone tell me how to wire up the matrix to the arduino, because the arduino doesn't have enough pins to run 2 colors of 8x8's
more than 3 colors ( R , G , RG ) would also be nice with the arduino :)
