From the README
System Monitor Lamp A USB lamp that lights up according to the CPU, network and disk usages of the host. Each metric is displayed as one color channel; green for CPU, blue for network and red for disk. The LEDs on the ring are split according to the number of CPU cores for the green channel. For disk and network the ring is split in two, left for input and right for output. How it works The Teensy firmware has support for Raw HID, which can be used to send arbitrary data from the host to the device where it can be interpretted as we wish to operate digital or analog pins. This project contains both code for the lamp and a service to run on the host computer.
