    電路圖箭頭朝里：PNP單極管；箭頭朝外：NPN的單極管小圓圈為插針。用一根杜邦線將插針與單片機引腳相連，單片機引腳輸出低電平，單極管導通，e、c連通，形成回路，有源蜂鳴器發聲；無源蜂鳴器需要（與蜂鳴器種類有關，實際使用時可測試）的音頻信號，即產生一個不斷的高低電平變化，高低電平變化頻率為3、單片機I/O口驅動能力非常微弱，不可以通過單片機I/O口直接驅動蜂鳴器，必須通過外接驅動電路，使R39電阻，單極管和R19電阻構成電流的放大電路從而可以驅動蜂鳴器，而不是依靠單片機管腳驅動蜂鳴器4、占空比：高電平時間方波：高電平、低電平時間相同~：取反符號，將管腳輸出電平狀態取反含有上拉電阻，默認輸出高電平。高低電平各延時一段時間。江蘇配電箱AD16系列蜂鳴器廠家AD16 蜂鳴器操作壽命超 5 萬小時，降低后期維護更換頻率。

    樓梯照明燈具怎么選擇樓梯等局部照明用選用落地燈、臺燈、壁燈、地燈，選擇燈具還要考慮燈具的尺寸和房間面積和高度適應的問題，燈的高度不要超過40公分為好，同時好選擇節能燈，它比較節電，市面上的價格也不算高。2室內籃球場照明燈一般是用什么燈室內籃球場照明有倆種布燈方式，一個是滿天星布燈，也是用的多的方式，還有一種是馬道布燈。一般滿天星布燈的話都是用的LED工礦燈，馬道布燈用的是LED投光燈，側裝可調照射角度。###普通白熾燈燈泡肯定是不行的,因為更換太過于麻煩,而且顏色偏黃。鹵鎢燈的溫度和功率普遍較高,個人推薦用較好的節能燈3led貼片照明燈好還是燈珠好建議買led貼片臺燈的,優點:1、光源方向性好,按需照明,作為應急臺燈較好。2、體積小,LED基本上是一塊很小的晶片被封裝在環氧樹脂里面,所以它非常的小,非常的輕。3、照度充足,滿足你的普通照明需求。4、耗電量低LED耗電相當低,一般來說LED的工作電壓是。工作電流。這就是說:它消耗的電能不超過。5、綠色環保,高效節能,LED是由無毒的材料作成,不像熒光燈含會造成污染,同時LED也可以回收再利用。6、無紫外線、無紅外線。堅固耐用,LED是被完全的封裝在環氧樹脂里面,它比燈泡和熒光燈管都堅固。 靜安區配電箱AD16系列蜂鳴器性價比
