SCUTTLE Project: https://mxet.github.io/SCUTTLE My Arduino code for this project: https://github.com/dmalawey/FastLED/blob/master/examples/ColorPalette/ColorPalette.ino It’s a WS2811 LED strip with 18 diodes, running an example code. Each LED is addressable and can be controlled for RGB intensities. The 12v battery pack powers this version of the lights (others operate with 5v). And the commands come from pin D1 on the ESP. It worked great! I recommend these lights for status indicators on your robot.
