  These are support functions (and settings( set the PWM (Pulse Width Modulation) output to "control" standard RGB LEDs or Strips
  This will not work if you have NeoPixel style LEDs (like WS2812), they requrie a different setup!
]]--

-- Configuration for the PWM/RGB output
--  If your RGB LED/strip is common anode (There's one positive lead and three negative [cathodes], which is common)

  CC-0 > No copyright claimed - You are free to use these snippets

These are a couple of functions used to fade between colors with an RGB LED (or strip).
This is made for the NodeMCU with LUA interpreter (Tested with Lua5.1.4 on SDK 1.5.4.1).
The only requirments are the PWM and TMR (timer) modules

NOTE: See (and include) rgb_pwm.lua (https://gist.github.com/ChrisHinde/0b0e6eaf2efa42faa4d6757d973caf13)
