Project created by Neoxelox for Hackster.io Arduino Contest 31/12/2016 
Cayenne MKR1000 Example 
This sketch connects to the Cayenne server using an Arduino/Genuino MKR1000 and runs the main communication loop. 
The Cayenne Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager. 
Steps: 
1. Install the Arduino SAMD Boards from the Arduino Boards Manager if you have not done so already. 
2. Install the WiFi101 library (https://github.com/arduino-libraries/WiFi101) from the Arduino Library Manager if you have not done so already. 
3. Select the Arduino/Genuino MKR1000 board and the correct port in the Arduino IDE. 
4. Set the token variable to match the Arduino token from the Dashboard. 
5. Set the network name and password. 
6. Compile and upload this sketch. 
For Cayenne Dashboard widgets using digital or analog pins this sketch will automatically 
send data on those pins to the Cayenne server. If the widgets use Virtual Pins, data 
should be sent to those pins using virtualWrites. Examples for sending and receiving 
Virtual Pin data are under the Basics folder.
