WHAT IS ARDUINO?

Arduino is an open-source electronics platform based on easy-to-use hardware and software. It’s intended for anyone making interactive projects.

3

HISTORY

Arduino project was made by a team of students and teachers from the interaction design school of Ivrea.

4

Gianluca Martino, David Mellis, David Cuartielles,Tom Igoe, Massimo Banzi et Nicholas Zambetti.

HISTORY

5

The inspiration come from processing, a programation language develloped in 2001 by Casey Reas and Ben Fry, two students of John Maeda from M.I.T..

ADVANTAGES

* Simple to use

* Cheap

* Open Source

* Multi-plateforms

7

PHILOSOPHY &COMMUNITYArduino project is based on a principle of open Source which has help it to have a quick developpement thanks to a community who work on the software and hardware.

There are several tools to share and learn:

- Blog (http://blog.arduino.cc/)- Forum (http://forum.arduino.cc/)- Wiki (http://playground.arduino.cc/)

ARDUINO = TWO THINGS

Hardware for prototyping Software for programing

10

PLATEFORM (HARDWARE)

Arduino is like a brain who going to make logical connections between an action and a sense. For example, if we read a text:The eyes (INPUT) see the image of the text, the brain (ARDUINO) read and make the interpretation for the mouth (OUTPUT) who’s make the sound of the reading text.

A LITTLE BIT OF LANGUAGE

pinMode() – Define your pin as an input or output.digitalWrite() – Send a binary value (high/low) to a pin.digitalRead() – Read a binary value (high/low) from a pin.analogRead() – Read a analogic value (from 0 to 1024) from a pin.analogWrite() – Send a analogic value (from 0 to 255) to a pin.delay() – allow a to make a break, arduino clock count in milliseconds.

26

FIRST INTERACTION

Plug your led like the image.

27

HOW TO PLUG A LED?Led have a way to plug it, one negative leg and one positive leg. Three ways to find the good way:

- Usually longest leg is +

- Truncate side is -

- The biggest part inside the led is -

+

28

int led = 13;

void setup() { pinMode(led, OUTPUT); }

void loop() { digitalWrite(led, HIGH); delay(1000); digitalWrite(led, LOW); delay(1000); }

FIRST INTERACTION

Try to change delay.

FIRST EXERCISE

Send a illuminated message using morse code.

31

PWM

Plug your led like the image.

WHAT IS A RESITOR?

Select example “Fade”:

examples/Basics/Fade

35

int led = 9; int brightness = 0; int fadeAmount = 5;

void setup() { pinMode(led, OUTPUT);}

void loop() { analogWrite(led, brightness); brightness = brightness + fadeAmount; if (brightness == 0 || brightness == 255) { fadeAmount = -fadeAmount ; } delay(30); }

37

WHAT IS A POTENTIOMETER?

38

READ THE VALUE OF THE POTENTIOMETER WITH ARDUINO

39

USE THIS VALUES TO LIGHT UP AN LED
