The Single USB RGB LED
This project is a single RGB LED that is controlled over USB using a command line interface from a serial terminal window. A PIC16F1459 microcontroller implements the USB communications device class (CDC), processes the commands received from the user, and controls a single APA106-F8 8mm round RGB LED. Continue reading

Piggybacking USB onto an Industrial Push Button
In this project, I mount the electronics from my single-key USB keyboard project to the back of an industrial mushroom push button switch. The finished big red button now activates my screensaver with a single overly-large button press. The biggest … Continue reading
