本设计已STC89C52RC单片机为基础，HS0038B为一体化红外接收头，恒流驱动采用的AMC7135芯片的红外控制全彩灯（1w的RGB-LED），程序中使用的遥控器用户码和编码和系统电路图已在文件里给出，每一部分已经分别进行注释方便大家理解，因PROTEUS不方便红外仿真所以不再提供仿真模型，由电路图可直接制作实物。(This design has been based on STC89C52RC MCU, HS0038B for integrated infrared receiving head, constant current driver using AMC7135 chip infrared control all the lights (1 w RGB LED), the program used in the user code and code and remote control system circuit diagram has been given in the file, each part has annotated facilitate everybody understand respectively, because of PROTEUS inconvenient infrared simulation, so no longer provide simulation model made physical circuit diagram directly. )
