Design and implementation of intelligent responder based on MCU
Abstract: The paper mainly designs a multi-functional responder,responder electronic devices for player or team.Is mainly the modern intelligent products applied to the real game,this paper mainly and implementation of the various functions based on Intelligent Responder design,the design by simulation in Proteus Software to complete the design verification of the theory.
This paper mainly through the STC89C51 microcontroller as the central control system, and is equipped with 16 players with the answer key set,on the other side of the host has two buttons, one is startup and reset button,start and return to a button,the other one is timing startup and timely start button, start time and start time is a key.At the same time with the sound alarm function, the whole design through the LED digital tube display. Based on the strong function of single chip,in order to make full use of the internal resources of the single chip computer,design of timer by MCU internal timer to complete the regular work.
Keywords: MCU; Responder; Digital control; Key
