I'm currently working with several younger kids, using the Arduino to teach programming. However, several have created short circuits, and now the connected USB port doesn't work (The Arudino is fine in a different port). Is there something I can put between the computer and the Arduino to protect from this. Something like a hub with serge protection, but I can't find anything like what I'm after.
There's to many to check every circuit and I know it's going to happen again, so I was wondering if anyone knew how to prevent it.
