here is my circuit. the FET-Control flag is connected to digital pin 7 of an Arduino, and the Shunt_Input Is Connected To AC-. (24VAC) The Arduino is outputting the 5v signal (4.7v), but for some reason the circuit is not activating (i.e. the heater is not heating up). I know I must be overlooking something stupid (either in my circuit or component selection), but cant seem to figure out what that is. Any ideas about what my problem is are appreciated. thanks.
