baby steps


Downloaded the Arduino software and scrounged up an led and a 100K resistor, plugged the Arduino board in and uploaded an example program and voila, I was adjusting the speed of a blinking LED with my touchpot in like 10 minutes. Meanwhile I'm researching bar graph array leds and reading more about multiplexing MAX7221s.
