继电器的测试实验，初学者的好帮手呀，看看(Relay switch control experiments)

说明：  串口发送,根据用户要求，可以有三种发送方式(Serial port transmission, according to user requirements, there are three ways to send)

AT89S52键盘程序,这是一个变频器的键盘驱动程序，简单，可靠，芯片为51单片机(one simple progrem for 51,if you like ,you can use it freely.)

基于stm32f103的超声波测距程序，利用keil编写(Ultrasonic ranging based on STM32F103)

该代码为本人的本科毕业设计代码，由于电路原理图丢失，不能提供原理图，但代码类每一个外设模块都有引脚的接口说明，代码也有详细的说明，代码风格与官方风格相似，本人在开发时比较注重代码的可读性，该设计是基于手机蓝牙和stm32单片机的一款RGB-LED变色变光远程+近程控制的智能灯，该代码仅提供参考，不可作为商业用途，若作为商业用途，产生的不良后果自行承担，在此声明！本人为初学者，代码仅供参考！(The code for my graduate design code, the circuit principle diagram is lost, can not provide the principle diagram, but the code class each peripheral module has pin interface that the code is described in detail, and the official code style is similar in style, I pay more attention to the readability of the code in the development, the design is intelligent variable light remote control + mobile phone Bluetooth and STM32 MCU RGB-LED a color based on the code for reference only, not for commercial purposes, if used for commercial purposes, adverse consequences borne, in this statement! I am a beginner, the code is for reference only!)
