【IOT物聯網應用-ESP32】第七篇：類比輸入使用光線感測器控制光感小夜燈

https://shop.mirotek.com.tw/iot/esp32-start-7/

ESP32可以將類比數值切成0～4095之間的表示範圍。ESP32類比輸入建議優先使用GPIO36、39、34、35、25、26這六根腳位。

類比輸入，是把外部元件輸入的高電位（5V）與低電位（0V）之間，切割成4095份（0~4095有4096個數字）。

因此使用類比輸接收外部元件訊號，不只可以得到高電位與低電位兩種狀況，而是可以得到多種狀況。

例如我們以類比輸入使用光線感應模組，不只得到環境光線檢測結果是亮或暗，而是可以有等級不

arduino error 問題解方燈環程式編譯問題 Adafruit_NeoPixel 版本問題 1140502

這個錯誤訊息：

Adafruit_NeoPixel.h:215:43: error: missing binary operator before token "("
#if ESP_IDF_VERSION >= ESP_IDF_VERSION_VAL(5, 0, 0)

代表您目前的 Arduino 開發環境或 ESP32 核心版本與新版的 Adafruit NeoPixel 函式庫（通常 v1.12.0 以上）之間有相容性問題。

這是因為 Adafruit_NeoPixel 在新版本中加入了 ESP-IDF v5 的檢查，但 Arduino IDE 的 ESP32 套件在編譯時未正確定義 ESP_IDF_VERSION，導致預處理器出錯。

🔧 解決方法如下（擇一即可）：
