What Is Arduino?Microcontroller PlatformOkay… but what’s a Microcontroller?!@#$#

Tiny, self-contained computers in an ICOften contain peripheralsDifferent packages availableVast array of size and power available

Microcontrollers!

So What Is Arduino?A physical Input / Output board (I/O) with a programmable controllerOpen sourceC/C++LanguageUSB programmableLarge communityInexpensive ~$30

An Image worth 1,024 WordsArduino is…

Why Arduino?It is Open Source, both in terms of Hardware and Software.It is cheap, the hardware can be built from components or a prefab board can be purchased for approx $30It can communicate with a computer via serial connection over USB / Bluetooth It can be powered from USB or standalone DC power.

Why Arduino?It can run standalone from a computer (chip is programmable) and it has memory (a small amount)It can work with both Digital and Analogue electronic signals - Sensors and ActuatorsYou can make cool stuff! Some people are even making simple robots, and we all know robots are just cool

HistoryThe project began in Ivrea, Italy in 2005 to make a device for controlling student-built interaction design projects less expensively than other prototyping systems available at the time.As of October 2008 more than 50,000 Arduino boards had been shipped.This has risen to more than 120,000 shipped boards as of February 2010.

Arduino is Open SourceProgramming environment is all Free SoftwareThe bootloader is Free SoftwareThe PCB board is under a Creative Commons License

What Can It Do?Input

Sensors (buttons, light sensors, ultrasound, …)Digital Input (Serial, SPI, I2C)

OutputLEDs & LasersLCD/OLED/Touch DisplaysSpeakersMotors, Servos, Steppers

Control and CommunicationDrive other machineryDirectly or using a communuication protocol

Sensors, Sweet Sensors…

Arduino HardwareArduinos differ in design but all share some basic functionality

AVR MicrocontrollerAmtel AVR Mega168 or AVR Mega 328Powered either directly or via USB power

CommunicationsSerial (older models)USB (most models)Connections to a USB interface (smaller models)
