  ArduinoCloudThing ReadAndWrite

  Example that explaines the use of read and write properties and how to
  manage a property of others devices.

  Arduino Cloud -> https://cloud.arduino.cc/cloud

  IMPORTANT: in order to establish the tls connection is necessary to add
  the arduino.cc SSL cerificate to your board, look at
  https://github.com/arduino-libraries/WiFi101-FirmwareUpdater#to-update-ssl-certificates
