Button 一个国外大学生毕业设计,用的是AVR单片机-Button a foreign university graduates design, the AVR

这是一段开始学单片机时写的LCD程序，基于普通的51单片机，在KEIL环境上开发的。-This is a period of time began to study single-chip LCD written procedures, based on the ordinary single-chip microcomputer 51, in KEIL environment developed.

本程序实现了基于74ls373锁存器的LED显示系统的Protues仿真。实例简单明了，适合初学者，在程序基础上进行扩展。-This procedure based on the implementation of the LED latch 74ls373 Display System Simulation Protues. Examples of simple and clear, suitable for beginners, in the procedures conducted on the basis of the expansion.

这是一套基于单片机的温湿度测量系统，里边附有设计的原理图，pcb图，以及烧写程序代码（keil c51编写的）。温湿度传感器使用的是dht11，性价比高。该系统除了能显示温湿度以外，还能设置温湿度报警阈值。设计的pcb板，小巧，使用。这是本人的毕业设计，有实物为依据，具有可操作性。-This is a single-chip microcomputer-based measuring system of temperature and humidity inside with schematic design, pcb plans, as well as the programmer code (keil c51 prepared). Temperature and humidity sensors are used dht11, cost-effective. Except that the system can display temperature and humidity outside, but also set the temperature and humidity alarm threshold. Pcb board design, compact, use. This is my graduation project, there is the physical basis of operational.
