Last year, I designed a solenoid control board based on Arduino UNO which is still working very well. The board was based on ATmega328p (arduino standalone) and used an optoisolator 6N136 to isolate the high power from the low power circuit and I used a MCP1406 as MOSFET driver for the FQP30N06L . N…
