Tanya Vasilevitsky Tatyana [email protected] Motivation

Bridge the gap between real (analog) world and computer (digital)

Process raw electrical data into computer logic Process computer logic to electrical signals

• A small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals.

• designed for embedded applications (remote controls , appliances, power tools…)

• Interrupts - real time response to events in the .

• Two ATMega PIC 18F8720 microcontroller i n an 80-pin TQFP package. Microcontroller

• 1971 - Gary Boone and Michael Cochran succeeded in creating the first microcontroller, TMS1000. Contained: ROM, R/W memory, processor and clock on single • 1976 - Intel develops Intel 8048 with massive success

• 1993 – EEPROM introduced (Replacing EPROM & PROM) & introduces first microcontroller with

• Today – 32bit Microcontrollers as cheap as 1$

Intel 1702A EPROM Single-board microcontroller

• A microcontroller built onto a single (PCB) • Provides all necessary HW: , I/O circuits, clock generator, RAM

Cheap, especially for development

Emphasis on IO (digital/analog)

The Make Controller Kit with an Atmel AT91SAM7X256 (ARM) microcontroller. Dwengo Arduino

Open source HW & Software company from Italy Started in 2005 as a project for students at the Interaction Design Institute in Ivrea, Italy

Initial team Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, and David Mellis

Arduino Vs Raspberri Pi Demo

• Arduino IDE • Selecting board type • Selecting com port • Setup & Loop • pinMode • digitalWrite • analogWrite • delay Ex1

• PWM – Pulse width modulation

• Light a led using PWM and video it – you will experience aliasing.

• Use the Aliasing to flash your ID • & record it. Have something to indicate time units • Be creative!

• Submission- Email to Amit on behalf of team containing ID’s and a video with your solution. Arduino Workshop kit
