本系统中使用了STM32F103VET6核心板、温度传感器DS18B20、lcd12864（串行）、直流电机模块、独立按键模块、蜂鸣器模块，模拟家用热水器的工作过程。除检测温度外，该系统在温度低于设定温度（系统初始设置50摄氏度）时电机旋转并且温度越低转速越快、核心板上的小灯按照特定规律（先由led0到led15逐个点亮再反向逐个熄灭再正向单个点亮）点亮；温度低于20度时增加蜂鸣器报警功能；独立按键可以调节用户设定温度大小。(A water heater system based on STM32. This system uses stm32f103vet6 core board, temperature sensor DS18B20, LCD 12864, DC motor module, independent button module, and buzzer module. In addition to temperature detection, when the temperature is lower than the set temperature (the initial setting is 50), the motor rotates and the lower the temperature, the faster the rotation speed is. At the same time, the small lights light up according to specific rules. When the temperature is lower than 20 , the buzzer alarm function is added.The independent key can adjust the setting temperature.)
