| Abstract: | This paper briefly introduces the principles of infrared remote control and the encoding/decoding methods of infrared signal. A countdown timer controlled by infrared signal is designed and implemented with an 8-bit single chip microcomputer AT89C2051 as its core. The transmission and reception of infrared signal are realized by ordinary remote controller of appliances and infrared receiver HS0038. The phonetic prompt is produced by using programmable speech chip API840N, This countdown timer has the advantage of simple design, high precision, and easy operation. |
