HID capable USB device
I created this as a workaround for typing in my annoyingly long password. it is just an Arduino pro micro modified to have a USB A connector instead of the mini USB connector that it comes with.
I added a switch and button to add extra functionality
In the .ino file you can see i soldered the switch to pin 3
You can program this to type anything, use it like a USB Rubber Ducky, etc.
