go run test.go : "signal: killed"

[Nalin Garg]

I am new to go and arduino. I wanted tried the sample code available on website on my Mac with following command :

go run test1.go 

and i get  error:

signal: killed 

My code looks like below:

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("ardunino", "/dev/cu.usbmodem1411")
        led := gpio.NewLedDriver(firmataAdaptor, "51")
        work := func() {
                gobot.Every(1*time.Second, func() {
                        led.Toggle()
                })
        }
        robot := gobot.NewRobot("bot",
                []gobot.Connection{firmataAdaptor},
                []gobot.Device{led},
                work,
        )
        robot.Start()
} 

Also when i try:

go build test1.go
gort arduino upload test1 /dev/cu.usbmodem1411

I get :

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00

But i tried running code on arduino IDE and things work just fine(led blinks):

/*
  Blink
  Turns an LED on for one second, then off for one second, repeatedly.
  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

  This example code is in the public domain.

*/
// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(51, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
  digitalWrite(51, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(51, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
} 

PS:

go version go1.7.4 darwin/amd64

gobot is installed in path

when i run gort scan serial i get "/dev/cu.usbmodem1411"

https://github.com/hybridgroup/gobot/issues/401 solved the problem along with running Firmata. 

But i still get error when i run :

go build test1.go
gort arduino upload firmata /dev/cu.usbmodem1411

error:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00

Am i doing something wrong?
