One of the nice things about the VUSB library is you can use cheap $2 chips for USB projects. I’ve used the PIC Microchips for years but now I’ve started adding USB to everything. Even these antique joysticks I found.
To make it easy to test some code I made a breadboard with the necessary zener diodes and resistors.
add a small protoboard
and some duct tape
and you have a nice quick way to try your code.
I tried making a simple control wheel with an encoder.
Works great as a volume control or even a photoshop controller.
