標(biāo)題: 求助:網(wǎng)上找來的單片機(jī)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(jī)的倒計(jì)時(shí)裝置，定時(shí)時(shí)間到后蜂鳴器鳴叫，倒計(jì)時(shí)結(jié)束，想添加一個(gè)控制繼電器功能，就是計(jì)時(shí)開始繼電器吸合，計(jì)時(shí)結(jié)束繼電器釋放，不知道怎么加，請(qǐng)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(jì)時(shí)是很簡單的程序，用c寫怎么這么長？對(duì)于匯編來說，只要在蜂鳴器不工作的時(shí)候加一條clr p0.1或者0.2任意端口拉低就可以用這個(gè)口驅(qū)動(dòng)繼電器了

蜂鳴器是0啟動(dòng)1關(guān)閉，那你可以用npn型三極管直接驅(qū)動(dòng)繼電器，當(dāng)蜂鳴器不響時(shí)繼電器導(dǎo)通，蜂鳴器響時(shí)繼電器關(guān)閉

感謝你提供的解決思路，蜂鳴器是計(jì)時(shí)結(jié)束時(shí)響5聲，如果用蜂鳴器的引腳驅(qū)動(dòng)繼電器，當(dāng)計(jì)時(shí)結(jié)束時(shí)就會(huì)重復(fù)開關(guān)5次，有可能對(duì)電氣造成傷害，不過現(xiàn)在問題已經(jīng)解決了！
