I ran into a bit of a wall with the Arduino Uno. It turns out as much as it is easy to interface with the Pi Zero W it has the wrong chipset and won't allow me to run the Keyboard.h or Mouse.h libraries. A few nights ago I stumbled on to the Seeeduino Xiao which might have just made the project better. It is ultra small, inexpensive and comes equipped with the chipset I need. I will find out more when it comes in the mail.
