Hi, I am putting together a simple circuit to turn a fan on from an ESP8266 NodeMCU. I am providing 12v DC to a Buck Converter to drop to 5v for the MCU, but was hoping to have a simple gate for the 12v to fan using a 2N 3904 Transistor. Originally I was considering a Relay in place of the 2N 3904 Transistor, but felt like that was overkill at 12v? Any advice appreciate, thanks.
