Arduino

Arduino is a single-board microcontroller to make using electronics in multidisciplinary projects more accessible. The hardware consists of a simple open source hardware board designed around an 8-bit Atmel AVR microcontroller, or a 32-bit Atmel ARM.

Arduino-Uno

It is founded by Massimo Banzi and David Cuartielles in 2005
• Based on “Wiring Platform”, which dates to
2003
• Open-source hardware platform
• Open source development environment
– Easy-to learn language and libraries (based
on Wiring language)
– Integrated development environment (based
on Processing programming environment)

– Available for Windows / Mac / Linux

The many Flavors (Types) of Arduino:-

• Arduino Uno

• Arduino Leonardo

• Arduino LilyPad

• Arduino Mega

• Arduino Nano

• Arduino Mini

• Arduino Mini Pro

• Arduino BT

Electric Inputs And Outputs:-

How to Download And Install its Software

• Download Arduino compiler and development environment from:

http://arduino.cc/en/Main/Software

• Current version: 1.0.1

• Available for:

– Windows

– MacOX

– Linux

• No installer needed... just unzip to a convenient location

• Before running Arduino, plug in your board using USB cable

(external power is not necessary)

• When USB device is not recognized, navigate to and select the

appopriate driver from the installation directory

• Run Arduino

Now Select your Board

Select Serial Port

Elements of the Arduino IDE

Arduino Sketch Structure

• void setup()
– Will be executed
only when the
program begins
(or reset button
is pressed)
• void loop()
– Will be executed
repeatedly

Using the Arduino IDE

Blink Example

Load the “Blink” example

(File-Examples-Basics-Blink)

void setup() {

// initialize the digital pin as an output.

// Pin 13 has an LED connected on most Arduino boards:

pinMode(13, OUTPUT);-----------------------------------------Use pin 13 as a digital output.

}

void loop() {

digitalWrite(13, HIGH); // set the LED on---------------------Set output HIGH.

delay(1000); // wait for a second--------------------------------Wait 1000 milliseconds.

digitalWrite(13, LOW); // set the LED off---------------------Set output Low.

delay(1000); // wait for a second

}

Compile, then upload the program

• Congratulations! you are now blinkers!
