基于单片机的霓虹灯控制器的设计 摘要 The Design of the Neon Lights controller Based on SCM Abstract This design uses the AT89C52 single chip microcomputer to control the neon lights. The?system?is?composed?by the infrared remote control module, the single-chip microcomputer control module, the display module and the speech module. Infrared remote control module is divided into the infrared transmitter and infrared receiver parts. After decoding through the single chip microcomputer, the infrared emission button address can be taken out in order to realize the remote control of infrared neon lights display. The infrared receiving tube only takes up one IO port. The display part uses the dot matrix module with 16 plus 16, through the single-chip control, it can display different patterns and the text, and make the word to move, pause, and switch from the current text to the other. The voice module uses voice chip ISD1730, which can record the desired voice, which can be played to introduce the design. It is support for pause, next, adjust the volume and reset of the voice playback. Due to the IO port of the microcontroller is not enough, this design uses a 74HC154 to expand the IO port, which is expanding the four-line to 16-line. The system has a strong practical value because of its advantages of simple circuit structure, easy operation and low cost.
