Concept
A coil becomes a magnet and pulls a slug / latch.
A little theory
Inductive kick — flyback diode mandatory. Inrush > holding current. In the classroom, treat 12V Solenoid Lock / Push-pull as a intermediate part using Driven via MOSFET/relay. Typical India street price is about ₹150–₹400. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project.
How it works in a project
IRLZ44/relay + 12 V supply + diode across coil. Pulse to unlock.
