This document provides an introduction to hardware hacking using Raspberry Pi and Arduino. It discusses why hardware hacking is interesting and rewarding as it allows interacting with the physical world. It then provides tutorials on basic projects like blinking an LED using Raspberry Pi and Arduino to illustrate hardware interfacing concepts. These include using GPIO pins on Raspberry Pi and digital pins on Arduino boards. The document encourages exploring additional capabilities like I2C, SPI and serial communication. It also introduces Arduino shields and provides examples of infrared communication and emulating human interface devices.

4. Why hack hardware?
•More interesting
•More rewarding
•Usually open entry point into an otherwise secure network
•Interacting with the physical world.

5. The Raspberry Pi
The computer geek’s electronics toy

6. Why Pi?
•Easily supports a large variety of languages.
•Comes with an Ethernet and USB ports.
•GPIO pins for hardware hackery
•Inbuilt RNG
•VideoCore GPU
•Linux!!!!

7. GPIOs
•Only digital
•26 in total
•Can be controlled through Python, C or a number of other languages
•PWM support exists, so does I2C, SPI and UART
•Can be set as input or output.

8. GPIO Pinout

9. Hack the Pi.
Lesson 1: LED blinky!

10. Hack the Pi
Lesson 2: Serial Hacker

11. Wiring

12. Why so serial?

13. Mayhem
Numero Uno

14. WhatDuino
•Open hardware project
•Official versions: Uno, Mega, Duemilanove, Esplora etc
•Compatible: Teensy, TinyDuino, Femtoduino,
•Shields, shields, shields!!!
•Multiple uses, single programming language!

15. Basic Overview
•14 Digital pins
•6 Analog pins
•Voltage regulated power supply
•Programmed over USB
•Inbuilt LED at pin 13

16. Shields

17. Lesson 1: ArduBlinky
int led = 13;
// the setup routine runs once when you press reset:
void setup() {
pinMode(led, OUTPUT); // initialize the digital pin as an output.
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
