NodeJSでシリアルポートを使っているArduinoを自動的に接続する方法

const SerialPort = require('serialport')

let path = ''
let ArduinoPort = ''

// Promise approach
SerialPort.list().then(ports => {
  let done = false
  let count = 0
  let allports = ports.length
  ports.forEach(function(port) {
    count = count+1
    pm  = port.manufacturer

    if (typeof pm !== 'undefined' && pm.includes('arduino')) {
      path = port.path
      ArduinoPort = new SerialPort(path, { baudRate: 115200 })
      ArduinoPort.on('open', function(){
        console.log(`connected! arduino is now connected at port ${path}`)
      })
      done = true
    }

    if(count === allports && done === false){
      console.log(`can't find any arduino`)
    }
  })
})

node portList.js

ここで結果
