2. Arduino …is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. http://arduino.cc

3. Physical Computing …is an approach to learning how humans communicate through computers that starts by considering how humans express themselves physically. - Tom Igoe http://www.tigoe.net/pcomp/blog/archives/notes/000169.shtml

5. Embedded Systems …are computer systems designed to perform one or a few dedicated functions. They are embedded as part of a complete device often including hardware and mechanical parts. In contrast, a general-purpose computer, such as a personal computer, is designed to be flexible and to meet a wide range of an end-user's needs. Embedded systems control many of the common devices in use today.. - Smart folks at Wikipedia http://en.wikipedia.org/wiki/Embedded_systems

6. Why Arduino? Inexpensive No need for external programmers, compiler licenses etc. Simple, clear programming environment All done in a simple IDE, no command line voodoo Cross-platform Works uniformly across Windows, Linux, MacOS Open Source! Both software and hardwre

9. Hardware Atmel Microcontroller ATmega328 (Duemilanove) / ATmega1280(Mega) ATmega8/ATmega168 on older versions ATmega644 for Sanguino Serial Bootloader STK500 compatible Support Circuitry Reset, Voltage Regulator, etc… USB/Serial Connectivity

32. BREADBOARDS ARE COOL!

33. The BreadBoard! * Drawn using the new Fritzing ( http://fritzing.org )

34. Arduino Software Based on avr-gcctoolchain and the Processing IDE. Code editor, programming tools and serial terminal all in one place.

35. Arduino Language Simplified C/C++ Based on the Wiring Project http://wiring.org.co Peripheral Libraries LCD, sensors, I2C, etc

36. Useful functions pinMode() – set a pin as input or output digitalWrite() – set a digital pin high/low digitalRead() – read a digital pin’s state analogRead() – read an analog pin analogWrite() – write an “analog” PWM value delay() – wait an amount of time millis() – get the current time http://arduino.cc/en/Reference/Extended

38. Example: SerialDisplay

47. LED Resistor Calculation Let’s assume we have a 9V source… R = V / I R = (9-3.4) / (20*10-3) R = 280 Ω Nearest standard value is 330 Ω List of standard resistor values: http://www.logwell.com/tech/components/resistor_values.html

48. Ohm’s Law V = Voltage I = Current R = Resistance V I R V = Current * Resistance I = Voltage / Resistance R = Voltage / Current

59. Example Project: Thermometer A temperature sensor is connected to an analog input on the Arduino Arduino periodically reports the temperature back to PC PC uses this data to plot graphs etc.

60. Thermometer: Arduino Code intsensorPin = 0; // the analog pin that the sensor is connected to void setup(){ Serial.begin(9600); } void loop(){ //getting the voltage reading from the temperature sensor int reading = analogRead(sensorPin); // converting that reading to voltage, for 3.3v arduino use 3.3 float voltage = reading * 5.0 / 1024; // print out the voltage Serial.print(voltage); Serial.println(" volts"); // now print out the temperature floattemperatureC = (voltage - 0.5) * 100; // converting from 10 mV per degree with 500 mV offset // to degrees ((voltage - 500mV) times 100) Serial.print(temperatureC); Serial.println(" degress C"); delay(1000); // wait a second } From Ladyada’s TMP36 Tutorial - http://www.ladyada.net/learn/sensors/tmp36.html

61. Thermometer: PC Side Read the incoming data every X seconds (cron) Collect and plot temperature graphs (rrdtool) Example: thermostat-graph http://www.anders.com/projects/thermostat-graph/ Not an Arduino project but easily hackable!
