灭火小车 机器人 。。。。 (use miehuo car)

STM32F103C8T6主控，SPI接口驱动RC522，使用USB转成虚拟串口直读A卡UID。(STM32F103C8T6 main control, SPI interface drive RC522, use USB to convert virtual serial port to A card UID.)

this is a c program paomaeng

RS485和232的转换电路 带隔离的转换电路 RS485和232的转换电路 带隔离的转换电路(RS485 and 232 exchange cercuit with isolated RS485 and 232 exchange cercuit with isolated)

对新手肯定会很有帮助，keil5环境下编译通过，在郭天祥TX-1C实验板上全部实现

调速 pwm 用滑动变阻器调整占空比调直流电机速显示(Adjustment of duty ratio DC motor speed indication by sliding rheostat)

基于51单片机的电子密码锁，密码可存于at24c02芯片，实现断电密码记忆功能，可修改密码(Based on 51 single-chip electronic password lock, password can be stored in the AT24C02 chip, to achieve the power password memory function, you can modify the password)

用adc0809转换 lcd12864做显示 测量 电压 电阻 加上热敏电阻测温度 测二极管极性和导通电压 (With adc0809 conversion, lcd12864 do show resistance measuring voltage, plus the thermistor temperature measurement, the measured diode voltage polarity and conducting)

说明：  用51单片机驱动有感直流无刷电机，程序有详细的注释，简单明了。(The inductive DC brushless motor is driven by 51 single chip computer. The program has detailed annotations and is simple and clear.)

51单片机中模拟串口的源码,可以拟补单片机中没有串口的缺点(51 microcontroller serial analog source, it can not have intended to fill shortcomings microcontroller serial port)
