What is Arduino? Open Source physical computing platform you can make your own board, or

buy one.

Arduino is an open-source platform used for building electronics projects.

Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer.

Very widespread, many projects openly available.

Extra HW (shields) available.

Why Arduino ? Well documented , a lot of examples and a great community

Open source Hardware/Software

Work on different OS (Linux , Windows and Mac)

USB connection

Cheap

Arduino Shields Shields are boards that can be plugged on top of the Arduino PCB extending

its capabilities. The different shields follow the same philosophy as the original toolkit: they are easy to mount, and cheap to produce.

Arduino Shields Arduino GSM Shield

Arduino Shields Arduino Ethernet Shield

Arduino Shields Arduino WiFi Shield

Arduino Shields Arduino Motor Shield

How does Arduino work? Write a code in your computer

Upload it to the Arduino board

Arduino board can the be used standalone

Arduino Language C like syntax, but simplified

Abstracts the pin naming to numbers

Trades efficience for ease of use

Easy to learn, yet powerful

Lots of example code

Easy to reuse C-code from other projects

Libraries can be written in C++

Lots of libraries available

Arduino IDE Examples

Examples Blinking led

Examples Blinking led

// Example 01 : Blinking LEDconst int LED = 13; void setup (){ pinMode(LED, OUTPUT); }

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

Declare variables

Initialize pins i/o

Program body

Examples Blinking led

Examples Blinking led with switch

Examples Blinking led with switch

// Example 02 : Blinking LED With Switch const int ledPin = 13; const int buttonPin = 2; int val;

void setup ( ) { pinMode(ledPin, OUTPUT); pinMode(buttonPin, INPUT); }

Declare variables

Initialize pins i/o

Examples Blinking led with switch

// Example 02 : Blinking LED With Switch void loop(){ val = digitalRead(buttonPin); if (val == HIGH) { digitalWrite(ledPin, HIGH); delay(1000); digitalWrite(ledPin, LOW); delay(1000); } else {digitalWrite(ledPin, LOW); } }
