[SCM] byshjimotorbaojingxitong DL : 0: 本课题采用STC89C51单片机作为主控制器，利用遥控开关来启动和关闭防盗报警系统，采用ND-1型全向震动传感器作为检测元件，当ND-1震动传感器检测到较大振动信号时，能够从第三脚输出直流电压信号，经过放大接入单片机I/O端口。单片机检测到ND-1有信号输出时，立即通过I/O口发出相应的信号驱动扬声器发出报警信号，同时将摩托车引擎锁住，到防盗报警的目的。-STC89C51 single-chip microcomputer used in this subject as the main controller, use the remote control switch to start and shut down anti-theft alarm system, the ND-1-type omni-directional shock sensor as a detection device, when the ND-1 vibration sensor detects vibration signal larger when feet from the third DC voltage output signal, after amplification access single-chip I/O port. Singlechip detected ND-1 signal output through the I/O port to issue the corresponding signal driver loudspeakers warning signal, motorcycle engine will be locked at the same time, the purpose of the anti-theft alarm.

[Software Engineering] Motion-Controlled-MP3-Player DL : 0: 一款MP3制作资料，很详细，附有原理图，源程序，从外国电子论坛搜罗的，欢迎下载-This is the third MP3 player project in succession. In this project, I designed it as a simple and small audio player compared to previous large scale graphic MP3 player project and implemented an additional strange gimmick. The MP3 player does not have any buttons nor dials that shown in right photo and it has an acceleration sensor instead of the mechanical switches. Therefore all playback commands to the player are given in defined motions, such as inclination, tilt and shock. The player detects the motion with the built-in acceleration sensor and recognize it as a playback control command. As the result, it came to not seem an audio player in appearance.
