我正在使用node-red上的项目来创建一个秒表。我在NPM中找到了计时器秒表，我想这将是我正在寻找的但问题是，我找不到启动秒表的方法。
我正在使用带有node-red和npm-contrib节点的raspberry pi来连接timer-stopwatch。每次我尝试注入命令时，调试控制台都会响应此错误：
TypeError：对象＃没有方法'重置'
我正在研究拖曳灯的这个项目，我希望秒表在绿灯启动时启动，然后一组红外传感器将成为秒表的停止信号。
在此之后，我希望秒表的结果显示在本地网页上，如果可能的话，在现场直播，并在实时部分下显示历史记录。
我正在寻找可以实现的任何方式。
起初我正在处理灯光的简单python代码，然后发现了节点红色，这有助于我理解。
这里是秒表的节点红色部分的剪贴板副本：
