心得:

    這學期因改回實體上課，多多少少需要校正回歸到之前的作息，上學期是因為在家實作Arduino專題，故時間較充裕，這學期則課業加重無法分配太多時間，但追根究底仍舊完成一份像樣的報告了。上學期因為是與其餘兩位同學一起合做，但其實當時都是我做的，網站、報告用的ppt等都是我個人製作，影片、接線材料也都是我獨自完成，但我在ppt上仍然寫其他兩人分配的工作(雖然當天我在線上報告時他們也沒上線)，等同於當時報告我獨自完成，可能也是因為這樣導致上學期分數偏低。當然也有一原因是因為報告的專題太過於簡單(一個人做也行)，但變成三人做一個專題，故分數也偏低，不過這學期我變成獨立製作，這樣也比較好。

    說完心路歷程後講講製作過程，雖然製作過程非常簡單，甚至接線也很簡單，程式碼的部分是可以延拓到n個matrix的排列，以及顯示不同的文字跑馬燈，這也是現今路上跑馬燈的原型，如果有機會的話，下學期希望將這份專題延伸，以及兼做Arduino月球車，月球車是循跡車+怪手的組合，故到時候會有兩組程式碼，分別代表操控這兩種模型。
