- 111. Serial Communication 利⽤用Aeduino上的Serial Library我們可以很容易的利 ⽤用任何⼀一種⼯工具語⾔言來跟Aeduino進⾏行資料傳輸與溝 通，以下我們將透過Apache來架設網⾴頁伺服器，並 利⽤用PHP的Serial⽅方法與Aeduino進⾏行溝通 ! ⾸首先安裝XAMPP這套整合軟體，其內建Apache + MySQL + PHP，可以幫助我們輕鬆地建⽴立網⾴頁開發 環境，接著只需要三⾏行PHP程式碼我們就透過網⾴頁 跟Arduino溝通囉！ XAMPP https://www.apachefriends.org/zh_tw/index.html =
- 112. Serial Communication XAMPP安裝完成後，打開manager-osx管理介⾯面 中的Manage Servers並按下右⽅方Start鍵，接著在 瀏覽器網址列地⽅方輸⼊入127.0.0.1或localhost，若 有看到XAMPP歡迎畫⾯面代表你安裝成功囉！ ! ! ! ! ! ! 若Apache Web Server無法啟動，請打開MAC終端 機輸⼊入sudo apachectl stop
- 113. Serial Communication 接著我們在應⽤用程式找到XAMPP資料夾，其中 htdocs中我們可以看到⼀一個名為index.php的檔 案，⽤用⽂文字編輯器打開index.php，刪除所有內容 後輸⼊入以下程式碼並存檔： ! <?php $fp =fopen("連接埠", "w"); fwrite($fp, 'a'); fclose($fp); ?> ! window作業系統在連接埠填⼊入如”COM?” mac作業系統則填⼊入如”/dev/tty.usbmodem?” 最後打開瀏覽器並在網址列中輸⼊入127.0.0.1，此 時網⾴頁會透過Serial傳送⼀一個⼩小寫的’a’字元給 Arduino，Arduino在接收到資料後便會將LED點亮
