win8無法驅動arduino的板子的解決方式

在win8下，arduino的驅動程式無法使用，是因為預設要有簽署的程式才能使用
，所以參考國外網站的解決方式如下

1. Windows Key + R    按下windows的圖示按鈕+R
2. Enter shutdown.exe /r /o /f /t 00    輸入指令 shutdown.exe /r /o /f /t 00
3. Click the "OK" button   按下OK
4. System will restart to a "Choose an option" screen 將會出現選擇選項的畫面
5. Select "Troubleshoot" from "Choose an option" screen選擇疑難排解
6. Select "Advanced options" from "Troubleshoot" screen然後選擇進階選項
7. Select "Windows Startup Settings" from "Advanced options" screen然後啟動設定
8. Click "Restart" button按下重新啟動
9. System will restart to "Advanced Boot Options" screen重新開機會有些選項選擇
10. Select "Disable Driver Signature Enforcement" 選第7項：停用驅動程式強制簽章
11. Once the system starts, install the Arduino drivers as you would on Windows 7
       再重新安裝驅動程式應該就ok了

Steps to install driver after Driver Signature Enforcement has been disabled:
1. Right click the Unknown Device in Device Manager
2. Select Update Driver Software
3. Select Browse my computer for software
4. Click Browse button
5. Select the Drivers folder under the location of your Arduino software installation. (Do not select the FTDI folder inside the Drivers folder)
6. Click OK
7. Click Next
