When working with automatic door lock projects, you often face a problem of voltage incompatibility. Suppose, the door lock operates at 12V DC, but your microcontroller cannot tolerate more than 5V DC.
Well, here is your solution. This is a "Door Lock Driver". You can use it for this DC 12V Solenoid Electric Door Lock.
Note: Product package contains only the door lock driver (not the door lock itself)
