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)
