Due to the owners restrictions on the video, you will have to watch the video on youtube.

I get this when I try to watch it…


Thanks for the heads up. I’ll put a note in the original post that it will have to be watched on youtube.

This is a great Idea, I saw the same thing but for the Arduino Uno last year.

I can remember debugging things where the ability to easily see if there is activity on a set of pins would have saved hours of fiddly debug and adding my own indicators etc…
