  <script type="text/javascript" src="https://cloud.boltiot.com/static/js/boltCommands.js">
  </script>

  <script type="text/javascript">
    // The following line will set the api key and device name. It will be auto-initialized by Bolt cloud.
    setKey('{{ApiKey}}','{{Name}}');
</script>

  <!-- In below line, We are calling the digitalWrite function from  boltCommands.js file to switch on the LED. -->
  <button onclick="analogWrite(0, 'A0');">ON</button>

  <!-- In below line, we are calling the digitalWrite function from boltCommands.js file to switch off the LED. -->
