What is Arduino®
Arduino®is an open-source prototyping platform based on easy-to-use hardware and
software. Arduino®boards are able to read inputs –light-on sensor, a finger on a button or a
Twitter message –and turn it into an output –activating of a motor, turning on an LED,
publishing something online. You can tell your board what to do by sending a set of
instructions to the microcontroller on the board. To do so, you use the Arduino
programming language (based on Wiring) and the Arduino®software IDE (based on
Processing). Additional shields/modules/components are required for reading a twitter
message or publishing online. Surf to www.arduino.cc for more information.

Programming Code
Whadda Bluetooth HC-05 module (WPI302/VMA302) example
This demo program uses a software serial port on pins 10 & 11 to connect to the Whadda
Bluetooth module.
Connect to the bluetooth module using your bluetooth enabled phone or pc. The BT device
name is "HC-05", the standard pincode is 1234.
Using a serial terminal app/program (e.g. Serial Bluetooth Terminal for android, coolterm
for PC) you can send and receive messages to/from the module.
If you send a 1, the LED coneected to PIN 13 will turn ON. If you send a 0, the LED will turn
off.
