loop 函式會執行一次之後再次啟動，如
此不斷重複直到您拔掉電源為止。練習
看看，修改程式讓 LED 以 0.1 秒的間隔
閃爍 20 次。
您 也 可 以 用 別 的 方 法 來 計 數 — 數 值 遞
減，使用 i--（i=i-1 的簡寫）；或是用等
差級數跳著數，若等差級數為 2，則指
令使用 i=i+2。
超越數位
目前，您都只用到數位變數：不是開就
是關，不是 1 就是 0。然而，真實世界並
不是非黑即白，黑白之間還有許多顏色。
類比感測器（如本書
第 132 頁“電位器與
電位計”
中的電位計）便可以提供黑白
之間的灰階部分。還有許多其他的感測
器，可以讀取不同的參數，幫助 Arduino
執 行 指 令。 由 Tero Karvinen、Kimmo
Karvenen、Ville Valtokari 合著的《Make:
感測器｜運用 Arduino 和 Raspberry Pi 感
測的專題與實驗》中，即介紹各種感測
器的教學實作。
我完全部分同意
前 一 個 章 節 中 所 看 到 的 腳 位 只 能 讀 取
數 位 訊 號。 可 喜 可 賀 的 是，Arduino 上
A0~A5 之間的所有腳位也可以讀取到類
比訊號，如
圖 16-10
所示。
範例 16-6
閃爍次數不至於閃瞎眼睛的指令
