The first post of many where I describe how to build a ESP8266 WiFi LED dimmer which can be remotely controlled using Domoticz. Is this due to using a MOSFETs and not needing the resistor on the base pin of a transistor? Secondly you have two MOSFETs. Because you use White only led strips that have a 12v wire and a signal wire does your
