Open Hardware

Refers to the design specifications of a physical object which are

licensed in such a way that it can be studied, modified, created, and

distributed by anyone.

Is a set of design principles and legal practices, not a specific type of

object.

Can refer to any objects—like automobiles, chairs, computers,

robots, or even houses.

Open Hardware - Electronics

“Source code" for electronic circuits—schematics, blueprints, logic

designs, Computer Aided Design (CAD) drawings or files, etc.—is

available for modification or enhancement by anyone under

permissive licenses.

Open Hardware Advantages

Faster developments

More accessories(in case of hardware , more shields etc), More apps

No need to reinvent the wheel

Increase popularity

Common Hardware

Mass Production- Reduced Price

Easy Troubleshooting

• A microcontroller board, contains on-board power supply, USB port to

communicate with PC, and an Atmel microcontroller chip.

• It simplify the process of creating any control system by providing the

standard board that can be programmed and connected to the system

without the need to any sophisticated PCB design and implementation.

• It is an open source hardware, any one can get the details of its design

and modify it or make his own one himself.

What is Arduino?


What Arduino is Not

• It is not a chip (IC)

• It is not a board (PCB)

• It is not a company or a manufacturer

• It is not a programming language

• It is not a computer architecture

(although it involves all of these things...)


So, What is Arduino?

It’s a movement, not a microcontroller:

• Founded by Massimo Banzi and David Cuartielles in 2005

• Based on “Wiring Platform”, which dates to 2003

• Open-source hardware platform

• Open source development environment

– Easy-to learn language and libraries (based on Wiring language)

– Integrated development environment (based on Processing programming environment)

– Available for Windows / Mac / Linux

Arduino Addons / Shields

• TFT Touch Screen

• Data logger

• Motor/Servo shield

• Ethernet shield

• Audio wave shield

• Cellular/GSM shield

• WiFi shield

• Proto-shield

Power input


• Micro controller : At mega 328

• Operating Voltage : 5V

• Input Voltage (recommended) : 7-12V

• Input Voltage (limits) : 6-20V

• Digital I/O Pins : 14 (6PWM output)

• Analog Input Pins : 6

• DC Current per I/O Pin : 40 mA

• DC Current for 3.3V Pin : 50 mA

• Flash Memory : 32 KB (0.5 KB boot loader)

• SRAM : 2 KB (ATmega328)

• EEPROM :1 KB (ATmega328)

• Clock Speed : 16 MHz


You can download the Arduino IDE

(The program used to write code and

uploading it to arduino boards) from:

http://arduino.cc/en/Main/Software

Arduino IDE:


http://arduino.cc/en/Main/Software

• Credit-card-sized single-board computer

• Raspberry Pi has Broadcom BCM2835

system on a chip (SoC)

• SD card for booting and long-term storage


RPi Models

Model B+ Model B Model A




• 10/100 BaseT Ethernet socket

• HDMI socket

• USB 2.0 socket

• RCA video socket

• SD card socket

• Powered from microUSB socket

• 3.5mm audio out jack

• Header footprint for camera connection


RPi Pin out


OS Support• Linux on a bootable SD card

• Fedora

• Raspbian

• Debian

• Arch Linux ARM


Programming

•By default, supporting Python as the educational language.

• Any language which will compile for ARMv6 can be used with the Raspberry Pi.


Applications

• It can make your Old TV in to a smart TV. (You can playVideos, 3D Games, Music, Browse Internet and muchmore.

• Raspberry Pi can Act as Full HD 1080p Media Player.

• Its a Mini Computer which just cost Rs.2,950/-

• You can connect a Monitor, Keyboard and Mouse anduse it as a normal computer.

• Its Graphics Capabilities is better than Apple Products.


Disadvantages• It does not have a Hard Disk associated with it for permanent

storage pf files,we have to connect one externally or have touse SD card for the purpose.

• The RAM is a POP package on top of the SoC, so it’s notremovable or swappable.

• There is no Real time clock associated with the board.Addingan RTC is expensive. You can add one yourself using the GPIOpins.

Open Hardware Challenges

Security:

Eg: hacking of traffic signals

Lose of Developers edge (?)

Eg: KFC

Not a real challenge
