Circuit Documentation

Summary

This circuit consists of an ESP32 microcontroller, a series of WS2812 RGB LED strips, and a USB male 2-pin connection for power. The ESP32 controls the LED strips, which are powered by the USB connection. The LED strips are connected in series, with the data output of one strip feeding into the data input of the next.
