Arduino 0022 & UNO; a breeze on 10.04 64bit, not on ubuntu 32bit

Nice. Try to always put in at least some delay in your loops, especially when sending serial data.

To prevent locking myself out time after time after doing the same thing I always add delay(3000) as the first line in my setup() function so that I have a few seconds to upload a new sketch or blank sketch before the program starts not matter how messed up the sketch on the board is.
