14x14 rgb matrix, how to start one?

I'm new to the arduino and i wanted to control a 14x14 common cathode rgb led matrix, idk where to start. any ideas?

Start by flashing a single LED, then control a single RGB LED, then control a single colour 8x8 matrix, then control an 8x8 RGB matrix, then control a 14x14 matrix, then post your circuit + code on the playground!

There are examples for EVERY step along the way up to and including the 8x8 RGB matrix on this forum, the arduino playground and other sites.

Play around with a single LED and single RGB LED using the arduino "official" examples, then start reading some forum threads and examples to learn about various design decisions you'll need to make, such as what drivers, code techniques etc.

tyvm, there's much to learn. :)
