Camera stops when capturing multiple times

[jigneshkumar.parekh]

Hi,
I am working on some "mailbox security system" and trying to capture the image when someone opens my mailbox. I'm using Tessel2 + USB Camera + Magnetic Switch. I followed the example in README file. It works great for the first time, but not after that.

Here is my code:

const camera = new av.Camera();

const board = new five.Board({
  io: new Tessel()
});

board.on('ready', () => {
  const door = new five.Switch({
    pin: 'a2',
    invert: true
  });

  door.on('open', () => {
    console.log(`--> Door is open....`);
    captureAndStartUpload();
  });

  door.on('close', () => {
    console.log(`--> Door is closed`);
  });
});

function captureAndUpload() {
  console.log(`--> Started capturing....`);
  const fileName = 'captured-via-data-event.jpg';
  const filePath = path.join(__dirname, fileName);
  let writable = fs.createWriteStream(filePath);
  camera.capture().pipe(writable);

  writable.on('finish', () => {
    console.log(`--> File saved....`);
    console.log(chalk.green(`--> Uploading to gDrive`));
    uploadFiles.uploadToGDrive(fileName)
      .then(fileData => {
        console.log(chalk.green('--> File created: ', fileData.name, ' with URL: ', fileData.webViewLink));
      })
      .catch(err => console.log(chalk.red(err)));
  });
}

Not sure if I'm doing something wrong here. May be I'm not closing the camera stream?
Please advice.
Many thanks in advance!
