Module protection leds WS2812B

Simple protection module for WS2812B LEDS with recommended capacitor and resistor with auto level up from 3.3v to 5v on data if necessary.

WS2812B are very tolerent but in long time use, without the recommended protection, the first pixel slowly die known as the firt LED syndrom or first pixel dying etc... We use a schmitt trigger to level up from 3.3v to 5v if necessary to avoid any problems from the low voltage.
