Fingerprint password lock based on 51

This design developed a fingerprint recognition electronic password lock system based on a single-chip microcomputer. The system uses STC89C52 microcontroller as the core of the module. It controls the ZFM-60 fingerprint module through serial communication to register fingerprints and store fingerprint data. It displays the comparison process and results through the HS12864-15C LCD, supplemented by DC relays and light-emitting diodes to simulate unlocking. Actions. This system has small size, high cost performance, fast transmission speed, and is suitable for families and organizations.

Principle hardware design and source code of self-balancing car

The self-balancing car uses the power of the car model to keep the car relatively balanced, which is a dynamic balancing process. The power to maintain the balance of the car model comes from the movement of the wheels, driven by two DC motors. The hardware of the car is divided into three parts, namely the main control part, the car attitude acquisition part and the motor drive part.
