NEOPixel RGB LED case light using ESP32 with Marlin on MRR ESPE board
Marlin 2.0 runs on the ESP32 microcontroller, and this is a test of the RGB features in Marlin using the MRR ESPE board. In Marlin, the light strip using NEOPixels has been configured as a case light. Separately, the fan is a RGB CPU fan that uses non-addressable RGB LEDs has been set up as an LED light in Marlin. Controlling the lights using the LED menu on the LCD controller will cause both sets of lights to change.
The MRR ESPA and MRR ESPE are 3D printer control boards that use the ESP32, which is a microcontroller with Wi-Fi. On Marlin 2.0, it can be used with the ESP3D web interface to allow 3D printers to be controlled with any web browser. While this was not used in this video, the gcode M150 can be used in the web interface to control the LEDs as tested in a previous video.

(There is a known glitch with addressing Neopixels using the Adafruit_Neopixel library on the ESP32.)
