商品簡介

八達通電子積木，您可以使用它們來構建電子項目，就像堆磚一樣簡單。通過使用八達通電子積木，您可以輕鬆連接Arduino/Freaduino兼容板與各種數字、模擬和I2C/Uart接口。這些無麵包板的牢固連接可用於廣泛的模組，如電位計、感測器、繼電器、伺服系統甚至按鈕，只需即插即用。 Octopus 無源蜂鳴器 Brick 是基於無源蜂鳴器，它可以通過 PWM 控制音量。區別在於有源蜂鳴器貼紙。

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

I2C掃描範例程式
