Design and production based on lithium battery charger_with schematic diagram and PCB

Since my four-wheel drive robot is powered by a 16.5V lithium battery, and there is no charger for this battery on the market, I am very confused about charging it. In desperation, we designed a portable and simple lithium battery charger. Solve the trouble of charging. The charger can output an adjustable charging current of 100mA-1A. The input voltage is VIN>18V, and it can be charged with the 19V voltage on the laptop. Charging time is generally determined according to the size of the charging output current.

STM32 smart home control system

This article designs and introduces a smart home control system based on GPRS wireless network with stm32 microcontroller as the core. This system is based on GPRS communication and can monitor the temperature and humidity status of the home in real time through wireless communication technology, and can freely control the switch operation of the home appliances. At the same time, the light intensity collection circuit is integrated, which can automatically open and close the curtain function.

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.
