Schematic PCB

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.

Schematic PCB

Real-time clock made by STC90C54RD+SD2405ALPI

I have an SD2405ALPI-G on hand, and I happen to have an STC learning board, so I made a clock with an annual error of about 2.5 minutes to play with. The schematic and program are all there. Now the hardware has a ringtone generating chip and a power amplifier chip, but the program has only initially implemented the function of displaying the day of the week, hours, minutes and seconds. It will be changed to an alarm clock when there is time.

Schematic PCB

One-handed aircraft somatosensory remote control based on sensortile

Use sensortile to make a somatosensory one-handed drone remote control, which can control the flight of the drone in various postures. It uses ppm control during simulated flight and 2.4G control during actual flight. The file is an mdk project, the chip used is stm32l4, and it has been tested on the simulator.
