3. Outline Week 1- Introduction, overview, breadboard, safety, rules, Fritzing, Components, Arduino IDE Week 2 - Ohms law, conventions, test equipment, Wire stripping and soldering, LED blinking Week 3 - Arduino hardware and software Week 4 and on - Various functions and combination setups

4. The Big Picture

5. Steps Define problem and goals clearly Develop flowchart and algorithm Select main components Develop hardware and software Put it together and test Iterate until goals are met

6. Circuit Elements Resisitors, Capacitors, Diodes, Transistors Integrated Circuits Subgroup of ICs  Microcontrollers (pic, Atmega etc.) Microcontroller development boards  Arduino

7. Breadboarding Provides connectivity Allows reconfiguration

8. Connectivity Under the Hood

9. Wiring Pattern

10. Soldering Make permanent connections on the PCB

11. Test Equipment Multimeter Oscilloscope Signal Generator Power Supply Logic Analyzer Hand tools

12. Multimeter Use to measure Voltage, Current and Resistance  Some measure frequency, capacitance, temperature and more *** Caution***  Take extra care when measuring current  Start with a selection higher than the highest expected value

13. General Architecture Participatory Environment ( Installation, Performance)  Sensing  Data Processing  Actuation and Feedback

14. environment sensing Computing Feedback & Actuators

15. Sensors Motion  Position, Acceleration, Rotation Pressure Light Sound Temperature Biometric sensors

16. Some Sensors

17. Data Processing Desktop, Laptop Single Board Computer (SBC, Raspberry pi, Beagleboard) Physical Computing Platform (Arduino, Parallax, mbed) Develop using a microcontroller (Pic, Atmega, 8051)

18. Some Processors

19. Introduction to the Arduino Environment Arduino Uno Arduino mini pro (5V, 3.3V, 8Mhz, 16Mhz) Arduino Mega Arduino Nano Arduino Due Arduino Yun ATmega Micro controllers Bootloader Installed Open Source IDE for Windows, OSx and Linux

20. Arduino Uno 14 Digital I/Os 6 Analog Inputs 6 PWM Outputs USB Connectivity and Programming USB bus or External Power 16MHz Clock and 32KB Flash Memory

21. Arduino Uno Cont’d USB Port External Power Digital I/Os, PWM, Serial Port Analog Inputs Power and Reset

22. Arduino Programming Simple Fast No programming hardware needed*

23. Sample Code Read a sensor  Data = analogRead(pin) Control analog devices(motor, light, etc)  analogWrite(pin, strength) Read a digital signal  digitalRead(pin) Output a digital signal  digitalWrite(pin, HIGH)

24. Output & Actuation Video displays, Projectors Speakers Lights Motors Haptic feedback devices

25. Actuators & Output Devices

26. Max/MSP Allows sophisticated audio and video manipulation and feedback Puredata for an OpenSource alternative with little graphics Many objects exist to interface with almost anything. Either direct or from 3 rd party developers.
