I am making a trunk open detection alarm that will detect that the trunk of my car is opend by using a photocell to capture the light from the dome light of the trunk when it is opend.
How would I go about soldering a circuit that would somehow activate a switch that would complete the circuit from a 12v line, triggering the alarm when the photocell is sending voltage.
the green box is where i need assistance
