使用约翰尼-5控制Arduino Mega坡道1.4

Question

我想用约翰尼-5控制一个阿迪诺·梅加和一个坡道1.4屏蔽。

我上传了标准Firmata的Arduino板，并尝试运行以下代码：

var five = require('johnny-five');
var board = new five.Board();
board.on('ready',function(){
   console.log('Board is ready');
});

我的错误：

1448365609699 Device(s) COM3,COM5
1448365609707 Connected COM3
1448365619710 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
enter code here
events.js:146
  throw err;
  ^

at Timer.listOnTimeout (timers.js:92:15)

有人知道为什么它不起作用吗？

Answer 1

var five = require('johnny-five');
var board = new five.Board({
port :"com5"
});
board.on('ready',function(){
console.log('Board is ready');
});

js文件没有连接到正确的端口。我需要把它设置为COM5。
