Before I start, let me explain why I'm trying to get into this hobby. I will be taking my first C programming class this coming semester and I thought programing a RGB LED matrix would be the best way to get my self familiarized with coding. I also enjoy doing projects like these, for some reason I really enjoy messing around with LEDs. I'm not sure if this too much of a project for a beginner like myself, but I enjoy challenges.
I have a few questions:
*How can I calculate which resistors to use on a 8 x 8 RGB Matrix through Arduino? *
I currently have a few 100 ohm 1/4w resistors in hand, but I really don't want to ruin my LED Matrix by using the wrong resistors to run the LEDs.
Any books or websites you recommend for me to read?
I've been reading the arduino reference, instructables and just purchased the "Arduino Cook Book."
Thanks much for your time.
