说明：   该程序不是标准的红外解码程序，只取了遥控板的按键码，区别出了0--9这10个按键。 注意：做这个实验时，请关闭日光灯，日光灯会干扰红外的解码。
(The program is not a standard infrared decoding process, just take the remote control keys code, distinguish the 0- 9 of these 10 keys. Note: do this experiment, please turn off fluorescent lights, fluorescent lights can interfere with infrared decoding.)
