title: how to send push notification to arduino
body: <p>I would like to know if there is anything like GCM for arduino.</p>
  
  <p>I'm working on a project where I need to send push notifications to the arduino connected with WiFi shield. Arduino then will do some action based on the notification it gets or sync up with the server data.
  Any advice on how I need to proceed would be helpful.</p>
  
  <p>Thank you. </p>
