SmartLiving Makers Arduino UART Demo Sketch
version 1.0 dd 25/11/2015
This file is an example sketch to deploy a digital sensor and actuator in the SmartLiving.io IoT platform.
### Instructions
1. Setup the Arduino hardware
- Use an Arduino Genuino 101 IoT board
- Connect the Arduino Grove shield
- Connect USB cable to your computer
- Connect a Grove push button to Pin D8 of the Grove shield
- Connect a LED to Pin D7
- Connect Grove wifi to pin UART (D0,D1)
2. Add 'ATT_IOT_UART' library to your Arduino Environment. [Try this guide](http://arduino.cc/en/Guide/Libraries)
3. Fill in the missing strings (deviceId, clientId, clientKey) and optionally change/add the sensor & actuator names, ids, descriptions, types
For extra actuators, make certain to extend the callback code at the end of the sketch.
4. Upload the sketch
Note: for use of extra actuators, extend the callback function at the end of the sketch
