我正在使用带有 Arduino Uno D1 Wemos ESP8266 的 Gobot。

$ gort scan serial
/dev/cu.Bluetooth-Incoming-Port     /dev/cu.usbserial-1410           
/dev/tty.Bluetooth-Incoming-Port    /dev/tty.usbserial-1410

$ cat blink.go
package main

import (
    "time"

    "gobot.io/x/gobot"
    "gobot.io/x/gobot/drivers/gpio"
    "gobot.io/x/gobot/platforms/firmata"
)

func main() {
    firmataAdaptor := firmata.NewAdaptor("/dev/tty.usbserial-1410")
    led := gpio.NewLedDriver(firmataAdaptor, "13")

    work := func() {
        gobot.Every(1*time.Second, func() {
            led.On()
            time.Sleep(1 * time.Second)
            led.Off()
        })
    }

    robot := gobot.NewRobot("bot",
        []gobot.Connection{firmataAdaptor},
        []gobot.Device{led},
        work,
     )

    robot.Start()
}

Arduino IDE 中示例中的其他程序按预期工作。我究竟做错了什么？
