I'm using Ro-Bot-X's uservotino for my Venux robot. I recently had a problem where the sketch (program, for all you non-Arduino types) disappeared on me. The board would power up fine, but nothing would happen. Then I upload the sketch again and everthing is fine.
I thought it was an isolated incident, but it just happened again! Any thoughts on what would cause an Adruino to lose its mind?
