PWM: RGB LED
############

Overview
********

This is a sample app which drives a RGB LED using PWM.

There are three single-color component LEDs in an RGB LED. Each component LED
is driven by a PWM port where the pulse width is changed from zero to a fusion
flicker threshold (the minimum flicker rate where the LED is perceived as being
steady), causing each component LED to step from dark to max brightness. Three
**for** loops (one for each component LED) generate a gradual range of color
changes from the RGB LED, and the sample repeats forever.

Wiring
******

Hexiwear K64
============
No special board setup is necessary because there is an on-board RGB LED
connected to the K64 PWM.

Building and Running
********************

This samples does not output anything to the console.  It can be built and
flashed to a board as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/basic/rgb_led
   :board: hexiwear_k64
