Too many new toys to play with:
This picture show an alaMode shield for the Raspberry Pi. The picture was taken without the shield being plugged into a Raspberry Pi. I had plugged it into one of my Raspberry Pi's and ran several test sketchs on the alaMode to blink a led, read temperature and show the changing light on the photo sensor.
The alaMode is an arduino board by itself, but allows the Raspberry Pi to easily communicate with the arduino micro controller and shields.
