I have been playing around a lot with my new Arduino [http://arduino.cc] lately. It has been incredibly interesting. Much fun to be had.

I have been doing some very basic stuff. Blinking Morse Code on an LED based on serial input, controlling the brightness or blinkrate of an LED based on a potentiometer... etc.

I have seen some very cool projects online, and in make magazine. For instance the remote controlled lawn mower, or lawn bot:

Or the Wii Nunchuck controlled camera:

Or the sun seeking solar panel array:
