Re: Some simple demo code?

Had some time to play around today. I'm working on a high-output rear LED for a bicycle. Man, is it bright! This code will flash the entire matrix on and off for random intervals. I'm sure I can come up with something more imaginative and eye-catching, but it is a start. #include <avr/pgmspace.h> in...

Some simple demo code?

Hey Paul, Newbie again. Your Arduino scrolling text code is way over my head. Could you post something simple like displaying a single, non-scrolling pattern, for a single board? Your kit instructions do promise "several Arduino sketches" for the board. I've only found the one. It's a brilliant kit....

Another Power Question from a Newbie

I'm looking to power a BBB and single 8x8 from a 12V battery as part of a bicycle lighting system (I'm going for a very bright "game of life" tailight). I'm using 20 mA LEDs, so looking a 1.2 A max. Can I replace the BBB voltage regulator with a LM7805 and plug the 12V into the BBB power jack? With ...
