• You can change the colors in the code, I used this simple color picker and copied the RGB color values into the code.

colorWipe(strip.Color(255, 0, 0), 10);  // Red (Device 1)
colorWipe(strip.Color(255, 255, 0), 10);  // Yellow (Device 2)
colorWipe(strip.Color(0, 255, 0), 10);  // Green (Device 3)
colorWipe(strip.Color(255, 0, 255), 10);  // Pink (Device 4)
colorWipe(strip.Color(0, 0, 255), 10);  // Blue (Device 5)

• You can directly charge the battery though ESP32-C3 Modules Type C, since this module have on board charging and overcarge protection feture.I hope you have fun making this project.
  Thank You!
