【问题描述】：

运行程序（节点Alarm_system.js）时，出现如下输出：

λ node Alarm_system.js
1514314162653 Available COM4,COM7,COM1,COM5,COM3
1514314162670 Connected COM4
1514314162673 Error Opening COM4: Unknown error code 1167
(node:4804) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Uncaught, unspecified "error" event. ([object Object])
1514314172672 Device or Firmware Error A timeout occurred while connecting to the Board.

Please check that you've properly flashed the board with the correct firmware.
See: https://github.com/rwaldron/johnny-five/wiki/Getting-Started#trouble-shooting

If connecting to a Leonardo or Leonardo clone, press the 'Reset' button on the board, wait approximately 11 seconds for complete reset, then run your program again.
events.js:165
      throw err;

【参考方案1】：

您只需配置正确的端口，如下所示：

board = new five.Board(
  port: "COM7"
);

之前的代码：

board = new five.Board();

我只需要指定正确的端口并获得正确的端口，您可以使用 Arduino IDE。这是一个很好的网站：ardunino setup project
