This experiment makes the use of Amarino shield from buildcircuit.com
If you have never worked with Amarino, I strongly recommend you to visit Amarino page and understand the basics of Amarino.

In this experiment, the sensor signal from LDR is fed to A1.

Steps:

a. Download Amarino and install on your Android Phone.

b. Download Amarino Library for Arduino and move it to the Libraries folder.

c. Download sensor graph(with LED controller) application and install on your phone. If you know Android Programming you can download the Android source code also. You can also get original Amarino source code from http://www.amarino-toolkit.net, but the original source code has only the Sensor Graph interface.

d. Download Arduino code and upload in your Arduino.

e. Stack your shield and Bluetooth adapter over Arduino. 

f. Activate Bluetooth function of your phone and note down the MAC ID of your Bluetooth adaptor and write it on the text box of your application.

g. Connect to the Bluetooth adaptor from your phone and operate the LED and see the LDR sensor’s response on the Amarino interface.

Note: The LED and LDR have been kept together so that LED light falls properly on the LDR and you can see the light sensor response clearly on the graph. If your room is highly illuminated, you can put piece of paper for better results.
