      it blinks and shines! great!!

      Did you try to drive a RGB led matrix?

      Hi Julien,
      This was just a test before I used a pair of max7221's to drive a long strip of 128 LED's. Driving an RGB matrix would be very cool though.. maybe a future project

      Hi Mike,
      I am new to electronics and I am just starting on my first project which happens to be with LEDs. What I need is a way of controlling 92 LEDs individual for different flashing rates. Will the max7221 work for this type of thing? Can I wire up the LEDs any way I wish?
      Thanks for the advice -Gideon.
