设计制作了一种智能台灯，主要是以BISS0001和单片机组成的红外传感控制电路。其特点是在有人时且外界光强较弱时能自动开灯，无人时关灯，节约能源；且能纠正坐姿，防止近视-Intelligent design a table lamp, and is based on single-chip component BISS0001 and infrared sensor control circuit. Its characteristics are in and the outside world when it was relatively weak light intensity can automatically turn on the lights when no one when the lights are turned off, energy conservation can correct posture and prevent myopia

用24L01的2.4Ghz无线控制风扇的源程序，产品是给美的电器做的，这是风扇接受部分，双向通讯-With the 2.4Ghz wireless 24L01 fan of source control, the product is to give the United States to do the electrical, which is acceptable to some fans, two-way communication

简单的功能介绍：本软件是由，三块模块组成。一个是打字练习，一个是打字计时，一个是音乐练习。本软件解决了打字练习途中的估噪无味，提升练习效果。本游戏有4个等级,可以根据情况来选择。这个软件还改进了，判断你是否打字失败功能。如果，打字失败，还可以从来，亦可退出。打字计时，为你打字计时间，提高效率。同时，电子琴音乐，为你在无聊时，增添色彩，可以练习歌谱，提高兴趣。-Simple, functional description: This software is, three modules. 1 is a typing exercise, one is typing time, a music practice. The software solves the assessed noise typing practice tasteless way to improve practice effect. This game has four levels, you can choose depending on the circumstances. The software also improved, to determine whether you have failed typing feature. If, typing fails, you can never can quit. Typing time for your time typing dollars and improve efficiency. At the same time, organ music, for when you" re bored, add color, you can practice song sheet, interest.
