亮度可调节LED灯，采用双色LED灯， LED调节亮度是通过调整通过它的PWM驱动电流大小得到的,节能灯一般是不能调整亮度的。本设计在项目中应用，绝对可以用。(Brightness can be adjusted LED lamp, using dual color LED lamp, LED adjust brightness by adjusting its PWM drive current size, energy saving lamps can not adjust brightness generally. This design is applied in the project, and it can be used absolutely.)

用于实现单片机16F648A和微控制器的通信。通过回车来确定通信是否成功，成功了可以从对应的LED开关看出，同时电脑终端会出现正确或错误的回复(This program is designed to convert 16F648A into a working micro-controller system which waits for one of a number of Carriage Return terminated messages and turn on or turn off one of four LEDs corresponding to the message. If the message is decoded successfully, an OK will be sent to the PC, otherwise an Error message will be returned )

变压器（Transformer）是利用电磁感应的原理来改变交流电压的装置，主要构件是初级线圈、次级线圈和铁芯（磁芯）。主要功能有：电压变换、电流变换、阻抗变换、隔离、稳压（磁饱和变压器）等。按用途可以分为：电力变压器和特殊变压器（电炉变、整流变、工频试验变压器、调压器、矿用变、音频变压器、中频变压器、高频变压器、冲击变压器、仪用变压器、电子变压器、电抗器、互感器等）。电路符号常用T当作编号的开头.例: T01, T201等。(A transformer (Transformer) is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) and so on. It can be divided into power transformers and special transformers (electric transformer, rectifier and transformer, power frequency transformer, voltage regulator, mine change, audio transformer, intermediate frequency transformer, high-frequency transformer, shock transformer, transformer, transformer, reactor, intersenser, etc.). Circuit symbols usually use T as the beginning of numbering. Examples: T01, T201 and so on.)
