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 Processor, Storage and RAM all in one tiny package! Atmel Microcontroller (MCU), typically Atmega328 Atmega328 Information ComponentSpecification Clock Speed16MHz Flash Memory32K EEPROM1K SRAM2K Analog -> Digital6Ch 10bit CommunicationSPI Digital14 I/O PWM6 Channel (Digital)

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

6. More Shields! LCD WIFI Zigbee MIDI LED Display

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: http://www.micromouseinfo.com/introduction/images/intro_hardware/PWM.gif +5VDC PWM Signal Ground 0-180 Degree Range of Motion We Get:

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

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