Hello guys!
I'm a new programmer and i wanted to know if I can use the Arduino MICRO to control a 5x7 LED matrix?
Actually I haven't even got the Arduino MICRO because when it's not possible to control the 5x7 LED matrix I'll buy the Arduino UNO.
Thanks for your helpful answers!
Hi there,
I am a beginner myself, but from what I can see the arduino micro has 20 digital I/O pins. If you plan on using single color LEDs and use simple multiplexing you can easily reduced the need pins down to 12 (5 for anodes and 7 for cathodes e.g.).
So yes this shoud be possible.
Somebody please correct me if I am wrong.

Yes.
Yes, but you really want to use a matrix driver - the MAX7219.
