Re: ESP32 powering a solenoid
The 1k resistor mentioned at some point to go between the GPIO output of your ESP and the base of the 2N2222 should be used between the GPIO output of your ESP and the gate of the MOSFET. This will limit the inrush current attempting to flow out the GPIO output into the gate of your MOSFET to establ...
