说明：  18B20数字温度计，驱动液晶显示的，可以实现报警功能(18B20 digital thermometer, to drive liquid crystal display, alarm function can be achieved)

国外PLC设计的原理图和PCB(Principle foreign PLC design and PCB)

单片机内刻录程序，包含C语言和汇编语言两个版本。实现7455C5与单片机的串口通信，信息传输。(Microcontroller burning program, contains two versions of the C and assembly language. 7455C5 microcontroller serial communication, information transfer.)

用VC进行单片机的串口通讯，并进行数据采集，进行处理以后在PC端显示(VC MCU for serial communication, and data collection, processing beyond the PC to display)

For this project you need a 3.7v power supply that prepared by LM317 regulator. So you need MAX232 for connect uart to pc .my AVR chip project is Mega8 that you can program on any Avr chip have 2kbyte rom. In bascom spi hardware don’t work correct, so I have to software spi ,but the software spi configure have low speed into hardware spi.

智能小车使用遥控控制的源代码，本代码可以作为进一步研究的参考(Smart car using the remote control of the source code, the code can be used as reference for further research)
