The document discusses using Arduino for developing interactive interfaces quickly and inexpensively. It describes the speaker's experience with Arduino projects, including stress games, domotics controllers, and an Arduino jam event. Arduino allows for fast prototyping of interactive projects through its inexpensive, easy to use hardware and software platform that has input/output pins and libraries to interface with sensors, displays and more.

7. Do you want to know the magic of
Arduino?
dinsdag 11 september 12

8. Arduino the basics
USB
14 I/O pins (20 on leonardo)
6 Analog input pins (12 on leonardo)
6 PWM out (7 on leonardo )
32 KB Flash memory 4 KB used by bootloader
dinsdag 11 september 12

9. Why the Arduino?
Based on existing languages: Wiring, processing (C-syntax)
Bootloader easy to compile and upload a sketch
Easy to use software
Good documentation
Big Community
Open Source = improved through community
Cheap

18. Digital In and Output (I/O)
pinMode(#, OUTPUT);
pinMode(#, INPUT);
digitalWrite(#, HIGH);
Set a pin state: HIGH or LOW
digitalRead(#);
Read out a pin state: HIGH or LOW
dinsdag 11 september 12

19. Analog to digital
0 to 5V = resolution of 0 to 1023

20. AnalogOut ?
Lets use PWM
PWM or Pulse Width Modulation
analogWrite(#,value);
Value: 0(0%) to 255 (100%)
Use :
dimming leds,
generate audio waves,
controlling servo and speed of motors
