About this project
Use of the httpclient
library to create a "thing" in dweet.io using an Arduino YUN.
/* LDR CONECTION.
----------------------------------------------------
LDR 10K 10K
+5 o---/\/\/--.--/\/\/---o GND
|
A0 o---------'
----------------------------------------------------
LM35 CONNECTION
Front view of the encapsulation. From left to right.
- Pin 1 --> +5V in the YUN
- Pin 2 --> Output to the A1 in the YUN.
- One 10kOhm resistor from this point to the GND.
- Pin 3 --> GND in the YUN

The center point from the divider of 10kOhm resitor and the LDR is connecte to the Analog input A0, its value is mapped from its min and max values meassured with min and max lighting to scale it into a range from 0 to 100, like of the 0 - 100% of the room lighting values.
The Timestamp of the readying is also added.
