Posted on September 12, 2007 by max

Here’s a little hack on HOWTO update your Arduino Chip from David Fowler. (Thanks David!)

If you ever wanted to get serious with some LEDs, you can really play with this guy. He can mimic any songs, well, it’s not available yet… I bet Garrett from Comfile can hack one up real quick… He made that voice activated Christmas Tree, this doesn’t seem too different.
