  1. Introduction to Arduino Chris Meyer Enlight Tech Talk - 2009 http://www.danielandrade.net/

  2. Arduino ARRRR, like a pirate / / DWEE, just say "do we“ fast / / NO, as in no. ”ARRR-DWEE-NO” http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1191602549%3Bstart=all

  3. What is Arduino? • Open Source Hardware Development Platform • USB Programmable Microcontroller (MCU) $30 Investment!

  4. Microcontroller? Miniature Computer Atmega328 Information • Processor, Storage and RAM all in one tiny package! • Atmel Microcontroller (MCU), typically Atmega328

  5. Shields? • Shields break-out/wire-up additional components to MCU Servo/Stepper/DC Motors Ethernet Prototyping GPS Audio / MP3

  6. More Shields! LCD MIDI LED Display Zigbee WIFI

  7. So What? • Previously, MCU’s were very difficult to learn to use • Required learning libraries, specialized protocols, timings, code minimization, 1,000+ page documentation

  8. Arduino makes it Easy! @Arduino.cc

  9. Use Arduino to Control Things • We’re going to: • Drive Servo • LED • Buzzer • Read analog voltage in

  10. Servo Control • Pulse Width Modulation (PWM) • We Provide: +5VDC PWM Signal Ground We Get: 0-180 Degree Range of Motion http://www.micromouseinfo.com/introduction/images/intro_hardware/PWM.gif

  11. Transistor Output • Use a transistor to “multiply” low power output from MCU to higher power to drive something Transistor Relay http://www.kpsec.freeuk.com/trancirc.htm

  12. Analog -> Digital • Take voltage signal and convert to discrete digital signal 5V 0V 1024 Bits 0 Bits Analog Input Digital Equivalent

  13. Analog -> Digital • Also have to worry about resolution of acquisition (Bit-Noise) http://zone.ni.com/cms/images/devzone/tut/dhall_analog_sig_0.JPG

  14. Pinout

  15. Demo Time!

  16. Questions? http://www.danielandrade.net/
