This application demonstrates how to publish data from an analog sensor with an Arduino Ethernet Shield to Sense Tecnic's IoT Platform community version (WoTKit). 

## Getting Started 

Download and install the latest Arduino software (http://www.arduino.cc/en/Main/Software). This guide assumes you have an Arduino board (http://www.arduino.cc/en/Main/ArduinoBoardUno) and an Ethernet shield (http://www.arduino.cc/en/Main/ArduinoEthernetShield).

## Create a WoTKit account

WoTKit is a community version of the STS IoT Platform, it allows you to manage, visualize and analyze data from sensors easily. Create an account at: http://wotkit.sensetecnic.com, its FREE! 

### Wire everything up

Our setup will be quite simple. We will be using a temperature sensor (LM35) connected to the A0 pin:

## Running the example.

You will need to set up your credentials in the Arduino sketch. This example uses Basic Authentication to make a REST request (POST) to the WoTKit to publish data. You can use a service like https://www.base64encode.org/ to create this string using your WoTKit credentials.

For example, using https://www.base64encode.org/ you can encode the following string: "yourusername:yourpassword" which will yield the string "eW91cnVzZXJuYW1lOnlvdXJwYXNzd29yZA==". Note this as it will be useful in the following line (remember to use your own username and password):

```

    client.println("Authorization: Basic eW91cnVzZXJuYW1lOnlvdXJwYXNzd29yZA==");

```

Compile and upload the sketch to your Arduino Ethernet shield and plug it in. You're done.
