通过对原始图像的水平和垂直投影图像来对车牌进行水平方向的定位(Original image through the level and vertical projection of images to the horizontal direction of the plate for the positioning of)

基于stm32的速度闭环，直流无刷电机驱动程序。(Based stm32 speed closed loop brushless DC motor driver.)

stm32输出四路pwm，能完成占空比可调，频率可变化的pwm(Stm32 four road PWM output, can finish the duty ratio is adjustable, can change the PWM frequency)

可以实现平衡小车的位置闭环控制，但是平衡时间不久，需要加入速度环控制(Closed-loop control of the position of the balancing car can be realized, but the speed loop control is needed soon after the balancing time.)

义隆单片机EM78P153SN 程序 100US延时 汇编语言(Elan microcontroller EM78P153SN program 100US assembly language delay)

本代码是基于标准c8051单片机的时钟打铃程序，主要实现的是数字时钟功能，可对时间进行调整，设定时间定时打铃，并且能随自己意愿调整铃声。(This code is based on the standard c8051 MCU clock bell program, the main achievement is the digital clock feature, which allows time to adjust, set the timer bell time, and can adjust the ring with their wishes.)

这是一个由STM32的MCU实现了脉宽调制输出的例子。(Generate PWM using STM32 MCU.)

“Coverage Control in Sensor Networks”，这本书是比较新的，是无线传感器网络覆盖国内外研究的总结，讲的很详细。(“Coverage Control in Sensor networks”,This book is a relatively new wireless sensor network coverage summary of the research, talk in great detail.)

PIC16F877A+LFN红外接送头+8位led，超简单的原理做红外实验，保证看了就懂，自主研发的哦！不用在看复杂的原理了(PIC16F877A+ LFN head+ 8 bits infrared shuttle led, the principle of infrared super easy to do the experiment, ensure that saw you ll understand, independent research and development! Don t look at the complex principle)
