dinsdag 11 september 12

3. Arduino projects
some small projects
Bicycle POV wheel display
Flashing psychedelic goggles
Electrofried a shocking game
Capacitance touch sensor, a button without a knob
helped friend and people online to improve there code
dinsdag 11 september 12

4. Arduino projects
CM interactive stress game
wire loop game on time
if you touch the wire you get a
time penalty

5. Arduino projects
Domotica controller with online
interface
dinsdag 11 september 12

6. Arduino Jam
20 Arduino enthusiasts
one big brainstorm starting from 2 themes
forming +/- 8 teams
developing
documenting
this all within 48 hours
dinsdag 11 september 12

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

10. Its easy to use!
5V Wifi shield Motor shield
Accepts 7 to 12V of input
Overcurrent protection
Lots of shields
Lots of libraries
dinsdag 11 september 12

11. How to start?
Download Arduino IDE
Plug your Arduino in
Select your Arduino Board
Open a sketch
Hit run
dinsdag 11 september 12

12. It‘s really that easy!

16. Lets get our hands dirty!
dinsdag 11 september 12

17. Arduino Sketch
global variable declaration
void setup()
void loop()
dinsdag 11 september 12

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
analogRead(A#);
dinsdag 11 september 12

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
dinsdag 11 september 12

21. Communication
Serial connection
to computer, 7 segment displays
SPI
ethernet shield, SD-card
I2C
sensors, eeprom, slave arduino
dinsdag 11 september 12

22. Arduino Interupt magic
