+## Bidirectional MOSFET level shifter
+
+To drive an addressable RGB strip along with ESP8266, you need to synchronize logical levels. 
+I usually use a simple MOSFET solution for single-channel shifting, hovever for multi-channel management, I would recommend using a simple Logic Gate IC like 74HC08 or a level shifter such as TXB0104.
