Can Someone help me to program an arduino uno?
I have an arduino uno and i wired a 3x3 led matrix to it. I really have no idea how to make any code for it to light up in any pattern or anything. I have the cathodes connected to pins 3,5,6. and the anodes connected to pins 9,10,11. Can anyone help show me a link or something that explains how to program it, or give me a sample code to use? thanks
