Grove - Gesture 上的感測器是 PAJ7620U2，它將手勢識別功能與通用 I2C 接口集成到單個晶片中。它可以識別 9 種手勢，包括上移、下移、左移、右移等，只需輕輕一揮手。
我們可以利用手勢來調節音量，控制機器人。或者我們可以製作一個遙控器，它可以通過手勢感測同時操作多個設備。

如何查詢I2C位址

操作流程

STEP 1. 將欲查詢的模組連接至Arduino UNO（附圖為腳位參考，實際請比對商品標示接線）

STEP 2. 開啟Arduino IDE並新增檔案

STEP 3. 貼入教學下方的範例文件，並上傳到Arduino UNO，即會開始掃描I2C位址

STEP 4. 開啟序列埠監控視窗，即可取得I2C位址
