基于单片机的室内空气净化系统
如果要将此应用项目移植到开发板上，只需要根据此项目的电路图修改管脚，改成我们开发板按键和LCD及蜂鸣器对应的管脚上，AD芯片使用的都是一样的，所以只需要将检测AD通道换成AIN3通道，也就是修改程序内通道的口即可。具体怎么修改通道口，参考基础实验例程内AD实验视频。(Indoor air purification system based on single chip microcomputer
If you want to apply this project transplanted to the development board, only need to modify the pin according to the circuit diagram of this project, we changed the pin development board buttons and LCD and buzzer on the corresponding, the use of AD chip is the same, so only need to detect AD channel for AIN3 channel, is modified the program within the channel mouth. Specific how to modify the channel port, refer to the basic experimental routines AD experiment video.)
