What is Arduino Platform? •
Arduino is an open-source electronics prototyping platform based o n flexible, easy-touse hardware and software. It brings simplicity to developer. –
Simplicity in Hardware, Development Environment and Language.
•
It can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators.
•
Arduino projects can be stand-alone or linked with software running on compu ters.

What can it do?
Smell Pollutants: Arduino interfaced with gas sensors. It can smell ethanol, methane and a bunch of voilatile organic compounds. http://www.instructables.com/id/How-To-SmellPollutants /
Mini Segway Using the Arduino: A self balancing segway-like robot is build by using arduino, a couple of LEGO motors and sensors. http://hacknmod.com/hack/make-a-mini-segway-usingthe-arduino/

Programming Arduino •
No need to write Hardware Abstraction Library (HAL) for accessing microcontroller‟s peripherals. That make it extremely simpler to program in Arduino.
•
All peripherals are in access with provided libraries e.g.
•
To configure pin as output or input:
pinMode()
To set a digital pin high/low: To read a digital pin‟s state: To read an analog pin: To write an “analog” PWM value: Wait an amount of time
digitalWrite() digitalRead() analogRead() analogWrite() delay()

For representing data in an intuitive way, LabView provide a powerful user interface along with its Microsoft Office toolkit for Data storage.
•
Through LabView you can control Ardiuno based Radon Measurement device via serial link.
•
Post processing could be done in LabView to avoid long code inside Processor.
•
Report generation in Excel..
•
Go to HELP in LabView and have a look on “Find Examples”….
