麵包板上的所有元件不可能愛怎麼放就
怎麼放。它們必須根據電路設計的規則
來相連。您可在電位計、喇叭、繼電器
與充電插座的端子透過焊接或電線來把
它們加入電路中。
如 果 需 要 更 強 壯 與 耐 久 的 電 路， 我 們
可 使 用 焊 槍 將 元 件 固 定 在 稱 為
洞洞板
（
matrix board
）的預先打好洞的板子上，
也可以自製
印刷電路板
（
Printed Circuit
Board
，
PCB
），如

量測
早些年，電流與電壓的測量工具的外觀
相當類似。某個腦中有偉大想法的人做
出了可量測這兩種物理量以及其他電子
特性的工具：
三用電表
（
multimeter
）。
三用電表有數位式與類比式兩種：類比
式是透過指針來顯示數值，由於它們可
直接量測訊號因此還是很普遍使用。另
一方面，數位三用電表則是在一個 LCD
小螢幕上顯示數值；訊號變化就是那些
在螢幕上不斷跳動的數值。
三用電表有一對輸入端，通常是紅色與
黑色的電線，末端有著筆尖狀的探針。
黑色探針是用來讀取共用或接地訊號（標
示為 COM 或 GND）。紅色探針則是用來
讀取我們想要知道的資訊—電壓、電阻
或安培—通常是用一個旋鈕來切換，如
圖 15-31
。
圖 15-31
三用電表的控制旋鈕已設定為測試二
極體
電壓是個相當容易量測的物理量。請確
認探針都已插入三用電表上的正確插槽：
黑色探針是 COM 插槽，紅色則是 V 或
