66mm WS2812B 16 RGB LED Ring (HCMODU0244)

This 66mm module contains a strip of 16 individually controllable RGB LEDs arranged in a circular serial configuration. Each LED has separately controllable red, green, and blue, elements which can be individually set to one of 256 different intensity settings, allowing over 16 million colour variations. The module also has power and data connections at both ends of the chain so that multiple modules can be connected together whilst still only requiring one digital pin to drive them.

What's more, to make controlling these LED's from an Arduino as simple as possible we have written our own exclusive library what will handle all the complicated bits. See bottom of this post or our blog for more information on this library and requirements.

  2.    DATE:    22/02/24
  3.    VERSION: 1.0
  4.    AUTHOR:  Andrew Davies
  5.  
  6. 11/03/15 version 0.1: Original version
  7. 22/02/24 version 1.0: DOUT pin defaults to pin 2 (this can be changed in HCWS2812.h)
  8.  
  9. This is an example of how to use the HCMAX7219 library to control one or more
  10. RGB LEDS. The example will set each LED to a random colour.
  11.  
  12. To use this example connect one or more LEDs in series (Dout --> Din) and connect
  13. the first LED's Din pin to digital pin 2 of your Arduino.
  14.  
  15. By default the library is set to control 200 LEDs. You can change this by editing the
  16. following line in the MCMAX7219.h header file:
  17.  
  18. #define NUMBEROFLEDS 200 <--- Change this number to match the number of LEDS connected
  19.  
  20. You can download the library from the software section of our support forum here:
  21. http://forum.hobbycomponents.com/viewforum.php?f=58
  22.  
  23. Or from Github here:

  25.  
  26. You may copy, alter and reuse this code in any way you like, but please leave
  27. reference to HobbyComponents.com in your comments if you redistribute this code.
  28. This software may not be used directly for the purpose of selling products that
  29. directly compete with Hobby Components Ltd's own range of products.
