I have a power supply that is being used to control a Electronic Magnet. Basically a magnetic switch goes to the Arduino, I read that signal to determine if the switch has been flipped. When it has been flipped, I want to turn the Power Supply offer. Typically there is just "Push" where I thought I would be able to put a High signal into, to make the Power Supply turn off but no luck. I have the Arduino PWM pin 2 connected to the "Push" on the power supply, I have it at LOW before switch is detected and High After. I tried connected the Ground of the power supply to the Ground of the arduino but it still didn't work. Any suggestions?
