What is an Arduino ?
1
• A board for anyone to build basic level
of intelligence into an object

The Arduino is a …
 Single-board microcontroller, intended to make the application of
interactive objects or environments more accessible
 Designed to make the process of using electronics multidisciplinary
projects more accessible
 Circuitry which executes instructions in programmable Integrated
Circuit

 Blinking LED
 Line Follow Car
 Obstacle Avoiding Robot
Simple Working…

Arduino can…
 Sense the environment by receiving input from variety of
sensors.
 Affect its surroundings by controlling lights, motors, and other
actuators.
 Support Standalone Applications
 Integrate with Computer / other process

Brief History of Arduino
 In 2005, a project was initiated to make a device for controlling student-
built interactive design projects that was less expensive than other
prototyping systems available at the time.
 Founders Massimo Banzi and David Cuartielles named the project after
Arduino of Ivrea and began producing boards in a small factory located in
Ivrea.
“…we started to figure out how could we make the whole platform even
simpler, even easier, even cheaper, even easier to use.. And then we started
to essentially re-impliment the whole thing as an open source project.”

Programming Environment
 The Arduino Uno can be programmed with the Arduino software
IDE(integrated development environment).
 The ATmega328 on the Arduino Uno comes pre-burnt with a Boot
loader that allows you to upload new code to it without the use of an
external hardware programmer.
 You can also bypass the Boot loader and program the microcontroller
through the ICSP (In-Circuit Serial Programming) header.
 Arduino IDE works on Windows, Linux as well as Mac Lion X
platforms.

 Ultrasound [ proximity range finder ]
 Actuators
 LED, other lights
 Motors
 Speakers, buzzers
 Display units

Blinking LED | Arduino
/* Blink Turns on an LED on for one second, then off for one second,
repeatedly. */
// the setup function runs once when you press reset or power the
board
void setup() { // initialize digital pin LED_BUILTIN as an
output.
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() { // the loop function runs over and over
again forever
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on
(HIGH is the voltage level)
delay(1000); // wait for a second

digitalRead(RS)) // Turn right
{
digitalWrite(RM1, HIGH);
}
