电路图
将其中一个蜂鸣器的正极连接到Arduino的9针和Arduino的10针的另一个蜂鸣器的正面。然后将两个蜂鸣器的负片连接到项目的Arduino.section的地面。
如何运行代码
首先,在Arduino IDE中粘贴为本文末尾的Arduino提供的代码并上传代码。
然后您需要从Wekinator的示例页面下载草图。
下载源代码以处理简单的10x10颜色网格。解压缩并在处理中运行代码。该程序将使用您的笔记本电脑的网络摄像头,根据您在摄像头前所做的操作,它将为Wekinator提供输入。
您需要另一个草图来输出Wekinator的输出。这篇文章末尾的草图代码。将其粘贴到处理中并运行草图。这个草图将从Wekinator输出并将其发送到Arduino,蜂鸣器将播放不同的声音。
两个处理窗口应如下所示。
现在打开Wekinator并进行如下图所示的设置。将输入设置为100,将输出设置为2.将类型设置为“自定义”,然后单击“配置”。
点击“配置”时“,一个新窗口将打开,如下所示。更改设置,如下图所示。
现在退出网络摄像头并点击“随机化”。开始录制半秒。
现在将右手显示在网络摄像头的右侧,然后单击“随机化”。然后开始录制半秒。
现在将左手显示在网络摄像头的左侧,然后单击“随机化”。然后开始录制半秒。
然后,单击“训练”,然后单击“运行”。现在,Arduino将根据您在网络摄像头前显示的手势播放声音。
