Functions to setup and control RGB LEDs/strips with Lua on NodeMCU

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)

Functions to fade between colors with Lua on NodeMCU
--[[ color_fade.lua
Created by Christopher Hindefjord (ChrisHinde / chris@hindefjord.se)
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)
