Test shield

I’ve been doing a lot of testing on my Arduino board and then one day I managed to burn one of the OUTPUT pins. Of course I never thought to have a hardware issue so I spend whole day searching for a mistake in my code, uploading and re-uploading, with no sucsess.

So I built a bullet-proof test shiend, that consist only of basic elements, LEDs connected to each output pin and a potentiometer connected to each analog input.

I also wrote a sample sketch, testing each port and then writing analog values to PWM ports, so I can test my board in a very short time.

Here’s the arduino code available, I can also include eagle files if anyone’s interested (only need to fix a glitch before publishing).

And some more pictures:
