What is Arduino Platform?

• Arduino is an open-source electronics prototyping platform based on flexible, easy-to-

use 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.

• Arduino Sketch

o Setup()

Initialization (run once at

beginning )

o Loop()

Run repeatedly

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()

Data Storage and Presentation(1)

• 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”….

• By using MS office toolkit in

LabView, you can generate detail

report of your measurements

including tables and graphs.
