I am trying to figure out how to go about using this Omron MOSFET relay in my project. I will be sending 12V (car voltage) to a radar detector and I want to be able to turn it on/off whenever via the Digital Pin on an Arduino board (max 5V output).
When the digital pin is high it allows 12V to flow to the radar. When the digital pin is low then it shuts out the 12V so no power is going to the radar.
Do I have the schematic above correct? Am I leaving something out?
