温湿度VB源码

车辆CAN总线的实时监测的电池容量，剩余容量，电压，电流和警报的其他参数(Vehicles can bus for real-time monitoring of battery capacity, remaining capacity, voltage, current and other parameters of the alarm)

说明：  本程序基于单片机实现RTC实时时钟，简单易懂(The program is based MCU RTC real time clock, easy to understand)

使用51单片机和18B20采集温度，并用数码管显示(Use 51 And 18B20 collecting temperature and with digital display)

stc12c5a60s_spi直接驱动st7920(12864) 串口驱动、只用个IO口(stc12c5a60s_spi direct drive st7920 (12864) serial driver, only with a IO port)

该项目首先是利用单片机对鱼缸的温度进行智能控制。首先通过外部按键对鱼缸所需温度进行设定。温度传感器 DS18B20 采集温度信息在外围的 LCD 上显示出来。其次是利用光电耦合器判断有无鱼饵，若无鱼饵，发出提示，若有鱼饵，则执行自动投食或手动投食功能。(The project first is the use of single-chip microcomputer to control the temperature of the fish tank. First, the temperature of the fish tank is set by the external button. The temperature sensor DS18B20 collects the temperature information to display on the periphery LCD. Followed by using photoelectric coupler to determine whether the bait, if there is no bait, alert, if there is a bait, automatic throw in and throw food or manually cast and functional food.)

直流斩波变化的仿真和一些参考文献 可以学习一下(The simulation of dc chopper change and some references can learn )

智能追踪小车，并且可以用遥控手动控制转弯加前后左右(Intelligent tracking car, and can be controlled manually with the remote turn around Canada)

利用easyx写的矩阵键盘仿真，希望可以给爱好者提供参考。(Use easyx wrote matrix keyboard emulation, hoping to provide a reference for enthusiasts.)
