課程回顧

1. What is your favorite homework?
我最喜歡我的期末作業，原本只是隨便找個題目去做，
順便挑戰一下自己的能力，雖然在製作過程中，
真的遇到了超級多瓶頸，但花了8個小時還是完成了，
這種成就感真的非常的大，尤其最後做出來後跟心裡想要的效果沒差多少就很開心，
所以這是我這學期最喜歡的一個作業，雖然有點辛苦，但真的很好玩!!!

2. What did you learn in this course?
學會用視訊結合程式碼做出想要的程式，
以前都是用既有的軟體來設計，
現在就真的是用自己寫出的程式碼來做，
這大概是我這學期最大的收穫，
以及能將程式集合硬體做出更真實互動的方式!!
真的非常棒!!!

3. What did you change after this course?
要對自己更負責任，
因為期中發生的一些事，
我從組別變成一個人一組，
所以整個期末都得靠自己的想法做出東西來~~
這應該是我最大的轉變吧~

00360124_期末專案

這次期末專案我要做 剪刀石頭布!!!

目前還不知道要怎麼判斷剪刀石頭布，

這大概是這次專案首先要解決的問題囉~~

皮膚偵測

今天的作業是皮膚偵測~~

做了鋼鐵人面具  超酷的!!!

隱形人

終於做出來了!!!!

隱形人想了一下，但其實跟LOGG的意思差不多!!!!

現在只差要解決光線問題就會完美了~~

今天的作業我整個DE了一整節課的BUG!!!

我的程式一直溢位....

最後才發現一個小小的關鍵 導致我程式的問題!!!

找到後真的超有成就感!!!

不過中間真的想到快發瘋了!!!!!!
