標題: 求助:網(wǎng)上找來的單片機程序,想添加控制繼電器功能
網(wǎng)上找來的程序，基于51單片機的倒計時裝置，定時時間到后蜂鳴器鳴叫，倒計時結束，想添加一個控制繼電器功能，就是計時開始繼電器吸合，計時結束繼電器釋放，不知道怎么加，請各位大佬幫幫忙，在此謝過了！

搞匯編的我真心看不懂這c語言，天書一樣，倒計時是很簡單的程序，用c寫怎么這么長？對于匯編來說，只要在蜂鳴器不工作的時候加一條clr p0.1或者0.2任意端口拉低就可以用這個口驅(qū)動繼電器了

蜂鳴器是0啟動1關閉，那你可以用npn型三極管直接驅(qū)動繼電器，當蜂鳴器不響時繼電器導通，蜂鳴器響時繼電器關閉

感謝你提供的解決思路，蜂鳴器是計時結束時響5聲，如果用蜂鳴器的引腳驅(qū)動繼電器，當計時結束時就會重復開關5次，有可能對電氣造成傷害，不過現(xiàn)在問題已經(jīng)解決了！
