This paper introduces the function of each module, the function of the circuits and the action of the components in the circuits. The design has the user to vote, the voting results and the number of votes for liquid crystal display function. This design can basically achieve the purpose of the conference voting, and have the advantages of low cost, good effect, and certain significance both for scientific research and market value. Key words：Wireless voting, single chip, LCD1602 display, keyboard module目 录第一章 绪论............................................................................................................................................11.1 引言...............................................................
