Arduino: Test Shield

Hi,
I've created a simple shield to test Arduino pin functions. It's an easy way to test, if all the processor pins function properly (I/O and ADC input). I did this because I have allready been able to burn some pins on two Atmega's, don't know exactly how, but I needed a fast way to test everything
Here are some photos :slight_smile:

Running LED's without series resistors is a good way to blow pins on the Arduino. At least add 100 ohm or more.

Actualy, I have SMD resistors, maybe not visible on the picture, but they are present :sunglasses:
