When 12V DC is applied to the coil, a magnetic field is generated that pulls the metal plunger (bolt) inward against the spring, retracting it and unlocking the door. When power is removed, the internal spring pushes the bolt back out into the locked (extended) position. This fail-secure behavior means the lock stays locked even during power failures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e Since the solenoid coil is an inductive load, always use a flyback diode (such as 1N4007) across the solenoid terminals to protect your driver transistor, MOSFET, or relay from voltage spikes when the solenoid is de-energized.\u003c\/p\u003e\n\n\u003ch2\u003eTypical Wiring Guide\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWith Relay Module (Recommended for Beginners):\u003c\/strong\u003e Connect the Arduino\/ESP32 digital pin to the relay module input. Connect the solenoid's two wires to the relay's NO (Normally Open) and COM terminals. Supply 12V DC to COM through the relay. When the microcontroller sends a HIGH signal, the relay closes and the solenoid unlocks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWith MOSFET\/Transistor Driver:\u003c\/strong\u003e Use an N-channel MOSFET (e.g., IRF540N) or NPN transistor (e.g., TIP120). Connect the gate\/base to the microcontroller pin via a resistor. Connect the solenoid between 12V supply and the MOSFET drain.
