co-owner of AppSaloon a Web-site/app development company

Maker

5 years of experience with the Arduino platform

Founder of the Arduino-jam


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


Arduino projects

CM interactive stress game

wire loop game on time

if you touch the wire you get a time penalty


Arduino projects

Domotica controller with online interface


Arduino Jam

20 Arduino enthusiasts

one big brainstorm starting from 2 themes

forming +/- 8 teams

developing

documenting

this all within 48 hours


Do you want to know the magic of Arduino?


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


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


Its easy to use!

5V

Accepts 7 to 12V of input

Overcurrent protection

Lots of shields

Lots of libraries

Wifi shield Motor shield


How to start?

Download Arduino IDE

Plug your Arduino in

Select your Arduino Board

Open a sketch

Hit run


It‘s really that easy!


What has a blinking light to do withInteractive interfaces ?


Arduino as a bridge

Reads out sensors

Collecting data

Communicate with devices

PCMacLinux

Sensors

Data

Internet


Arduino as stand-alone

Sensors

Data

Internet

Reads out sensors

Collecting data

Communicate with devices

Process data

Led

Lcd

character display

Internet

...

Motor

Servo


Lets get our hands dirty!


Arduino Sketch

global variable declaration

void setup()

void loop()


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


Analog to digital

0 to 5V = resolution of 0 to 1023

analogRead(A#);


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


Communication

Serial connection

to computer, 7 segment displays

SPI

ethernet shield, SD-card

I2C

sensors, eeprom, slave arduino


Arduino Interupt magic

Do something when you where doing something else, controlled by a input

Hardware interrupts on pin 2 & 3


Arduino the Limitations

Program size is limited to 28KB

Limited amount of pins

16 MHz clockspeed


User cases


CM stressgame

60 leds

3 IO inputs

1 analog potentiometer

Sound out


Solutions

60 leds in a matrix with shift registers

2 interrupts to detect touch

1 analog read of potentiometer ( linear )

second arduino for sound


Electrofried shocking game

2 buttons

10.000 volt shock


OfficeDuino

ethernet connection

Power control

3 PWM signals

2 on/off states

Current sensor

temperature sensor


Arduino Jam: Nipkow disc


Arduino Jam: Reversed GeoCach


So prototyping some Interactive Interfaces with Arduino?

It’s cheap

Easy to learn

Prototyping can be done very fast

And it can fly

YES
