7/22實作研習順利完成，感謝大家的幫忙，場地收拾得很乾淨，希望下次能夠有類似的課程再來一起maker一下
上完課發現講義有很多地方要補充：
0. 材料採購與前置作業
    淘寶購物方式
    材料預先分配
    杜邦母頭與排針連接時，需角度一致
    Sharp感測器杜邦母頭，壓接難度高，需預先製作
2. 各元件接腳數量與用途，可用Fritzing程式說明
3. ardublock說明
4. Sharp感測器測試、4LED、DHT22等，測試程式說明
6. 感測器final程式說明，錯誤樣態說明，除錯
    一開始出現fail，為esp8266接線錯誤
    9v電池電流不足，無法驅動整個感測器
8. 中間下課休息時間安排....sorry，有點趕，沒注意到
完成之後會再請大家幫忙看看，若還有哪些不足的地方，也請留言，感謝您。

網頁的PM2.5濃度判斷程式好像有誤喔！？
比如PM2.5濃度為35.3時，依照指標對照，應該為第三級深綠色，但卻判斷為第四級黃色，可否查查看，謝謝。

收到！可能設定判斷敘述有缺漏，明天修改完再跟大家報告，感謝李老師的協助。

如果還有老師研習後回家無法上線的，小弟這裡分享一下方式(摸索了快一個小時才搞定)
1.安裝arduino程式
2.將下載的檔案(ardublock-beta-20140828.jar)放到arduino資料夾中 (X86)，tools/ArduBlockTool/tool 的資料內即可,如果原先沒有的資料夾,要自行建立出來(大小寫要相符)-----這一步驟我有做，不過不知道要不要做，請老師解惑一下。
3.下載 DHT22的程式庫(這一部分沒有做，第三步驟arduino程式會出現錯誤)

DHT22的程式庫需另外下載，請在Arduino IDE程式的[草稿碼]→[匯入程式庫]→[管理程式庫...]

搜尋DHT22，點選，安裝

4.修改(LED4_Buzzer_DHT22_ESP8266_Relay_air2_sample)(本來以為還要插上USB修改wifi模組來更改網路設定，後來發現只要改這個sample檔就好，走了好多冤枉路)
改網路、更新時間，上傳時記得麵包版斷電

彥文老師超棒的！感謝你提供寶貴經驗

真不好意思，第二步驟的Ardublock其實是可以不用做的，是想要讓老師們體驗像Scratch一樣用積木來寫程式，當然不可能整個pm2.5程式都用Ardublock，只是想帶大家寫一下Blink
執行方法如下圖


Ardublock操作畫面，自己拉出Blink範例程式


我會再把內容補充到講義上面，大家可以想想如何用在教學喔！

學校經緯度座標要怎麼輸入呢？

有源蜂鳴器只需要HIGH或LOW,只能叫或不叫,pitch.h可以省略
若要用pitch.h發出音階聲音應該用無源蜂鳴器

宏儒老師好
請參考新錄製的「用Google Map取得GPS座標」教學影片，有字幕喔！要自行點下方的字幕按鈕。麻煩參考一下。

程式已經設定好String PMgps = "23.065177, 120.197872";   //學校經緯度座標

可是出現下面狀況：

SEND: AT
RECEIVED: OK after AT Command
Data ready to sent!
Send AT+CWMODE=1
SEND: AT+CWJAP="TN-Computer-bridge","computer123"
Waiting for 15 second to connect network .....

SEND: AT+CIPSTART="TCP","pm25.tn.edu.tw",80
SEND: AT+CIPSEND=93
>GET /xoops/api.php?schoolcode=213634&no=0&pm25=6.84&t=30.50&h=32.40&gps=23.065156120.197861
RECEIVED: OK

怎麼還是23.065156120.197861
逗號不見了

回檢測網看學校數值~經緯度也沒出現

確定一下，有沒有真的改到，有沒有確實上傳，會不會前面有兩條斜線// ？
