RTFM

Hi,

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.

There are few things in life more embarrassing than discovering you've failed to follow advice you've offered others.

And most of them involve somebody getting arrested, so you should actually consider yourself "lucky" :smiley:
