<p>讀者也可以在作者 YouTube 頻道(<a href="https://www.youtube.com/user/UltimaBruce">https://www.youtube.com/user/UltimaBruce</a> )中，在網址<a href="https://www.youtube.com/watch?v=-B-Ao0mh43U&amp;feature=youtu.be" target="_blank">https://www.youtube.com/watch?v=-B-Ao0mh43U&amp;feature=youtu.be</a> ，看到本次實驗-我們可以看到投幣前，投幣數為零，可使用時間也為零，所以不能使用電力，但是我們看到投幣後，投幣數累加一，可使用時間也累加，當使用時間大於零時，我們就可以使用電力，所以可以看到右邊的檯燈亮起來。</p>
<p>當然、如下圖所示，我們可以看到投幣計數器測試程式四結果畫面。</p>

<p>Arduino 投幣計時器最重要的事：當我們投幣之後，產生可以使用的時間，我們系統必須發現有可用時間時，必須啟動電力開關(<a href="file:///D:/%E5%B7%A5%E4%BD%9C/PCHome/248/9%E6%9C%88%E7%AC%AC%E4%B8%80%E7%AF%87/%E4%B9%9D%E6%9C%88%E7%AC%AC%E4%B8%80%E7%AF%87V3.doc#_ENREF_5">曹永忠, 許智誠, et al., 2015c</a>, <a href="file:///D:/%E5%B7%A5%E4%BD%9C/PCHome/248/9%E6%9C%88%E7%AC%AC%E4%B8%80%E7%AF%87/%E4%B9%9D%E6%9C%88%E7%AC%AC%E4%B8%80%E7%AF%87V3.doc#_ENREF_6">2015d</a>, <a href="file:///D:/%E5%B7%A5%E4%BD%9C/PCHome/248/9%E6%9C%88%E7%AC%AC%E4%B8%80%E7%AF%87/%E4%B9%9D%E6%9C%88%E7%AC%AC%E4%B8%80%E7%AF%87V3.doc#_ENREF_13">2015k</a>, <a href="file:///D:/%E5%B7%A5%E4%BD%9C/PCHome/248/9%E6%9C%88%E7%AC%AC%E4%B8%80%E7%AF%87/%E4%B9%9D%E6%9C%88%E7%AC%AC%E4%B8%80%E7%AF%87V3.doc#_ENREF_14">2015l</a>; <a href="file:///D:/%E5%B7%A5%E4%BD%9C/PCHome/248/9%E6%9C%88%E7%AC%AC%E4%B8%80%E7%AF%87/%E4%B9%9D%E6%9C%88%E7%AC%AC%E4%B8%80%E7%AF%87V3.doc#_ENREF_15">曹永忠, 蔡佳軒, et al., 2015a</a>, <a href="file:///D:/%E5%B7%A5%E4%BD%9C/PCHome/248/9%E6%9C%88%E7%AC%AC%E4%B8%80%E7%AF%87/%E4%B9%9D%E6%9C%88%E7%AC%AC%E4%B8%80%E7%AF%87V3.doc#_ENREF_16">2015b</a>)。</p>

<p>本文內容主要是介紹讀者投幣計時器核心程式，主要可以讀取時間，耗用時間，讀取投幣器與顯示，進而控制電力開啟與關閉。</p>
<p>本文到此，我們發現已經完成一個投幣計時器的核心功能，也達到市售投幣計時器的主要功能，下篇文章我們會進入物聯網的主題，將這些資訊全部傳送到物聯網。</p>
