/*
This example code is used to connect the Ubidots cloud service (Official homepage: http://www.ubidots.com).

 The device required is just:

 1. LM35 low cost temperature sensor or any device you used to upload data
 2. And Wido

 Note: Please don't forget to change the setting below before using!
 1. WLAN_SSID & WlAN_PASS
 2. API_key
 3. Device ID
