I'm EE challenged and have been working on figuring this out all morning. Please let me know if this will work.
I am trying to come up with a simple power switching circuit that will turn a heating element on during the day and off at night.
I use the lamp set at 12vdc/15W to match the specs of the heating pad.
The photoresistor I plan on using is 0.5Mohm (500k ohm) dark resistance and 10-20kohm light resistance. So I used the switch with the two resistors to represent the photoresistor.
My power source is going to be 12v.
And I have two types of N-channel mosfets on hand for the switching. IRFZ44n and IRF540 - I set the mosfet settings based on community recommendations and built around the Z44n.
