RC Car Meets Arduino
Jun 07, 2012, 10:04 pm
Just spent a few hours soldering up not one, but two 8*8 LED Matrices. I saw 8 pins on one side and 8 on the other so naturally set to work soldering on some printer ribbon and some headers. Its only now that I plug them in and nothing works as expect that I have started search for pin outs and found out that the rows and cols are all over the place.
RTFM for next time.
then watch this
