I am seriously considering building some projects usign the Arduino Uno, this is a small microcontroler mounted on PCB with it's own BUS. The bus can be attached to a number of Sheilds. A sheild is an add on module that allows you to connect various devices easily, Such as the ethernet sheild or I/O sheild.
The device is is dirt cheap, I jsut have to learn the coding for it and have a play.
So after my holiday.... BRING ON THE UNO!!
(actualy we will be playing UNO the game on holiday no doubt..)
