What is Arduino Platform?
•
Arduino is an open-source electronics prototyping platform based on 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 computers.

What can it do?
Smell Pollutants:
Arduino interfaced with gas sensors. It can smell
ethanol, methane and a bunch of voilatile organic
compounds.

Mini Segway Using the Arduino:
A self balancing segway-like robot is build by using
arduino, a couple of LEGO motors and sensors.

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:
digitalWrite()
To read a digital pin‟s state:
digitalRead()
To read an analog pin:
analogRead()
To write an “analog” PWM value:
analogWrite()
Wait an amount of time
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”….
