The document discusses introducing attendees to building Internet of Things (IoT) prototypes using Arduino microcontrollers. It covers connecting sensors and devices, programming microcontrollers to control inputs and outputs, and using networking hardware to connect devices. The workshop aims to help attendees create a working prototype and better understand the hardware that powers IoT. It will cover basics like making an LED blink and building prototypes that incorporate buttons, potentiometers, and programming code.

2. #1 DIGITAL MAKER – NEW TECHNOLOGY BEHIND THE IOT
“Internet of things” is on everyone's lips. Most
know that it is about connecting your fridge
with your smartphone or your coffee-maker
with your alarm clock. A huge market is
emerging. But only few understand the
hardware behind the measurement/sensors
and respective visualization. Learn how easy,
cheap and fast it is to build working
prototypes for your idea.
At the end of this hands-on workshop you will
have created a working prototype including
an Arduino microcontroller, buttons, LEDs,
resistors and all those things you won't
normally touch without asking your favorite
electrician.

3. INTERNET OF THINGS

4. o connected objects (“things”)
o autonomous communication
o variety of scenarios
o infrastructure and energy management
o medical and health monitoring
o home automation
o …
o privacy and autonomy?
#2 INTERNET OF THINGS – BACKGROUND
1 WHAT IS IT?

5. #3 IoT MARKET – JUST AN IDEA?

6. #4 IoT MARKET – WHAT WILL BE YOUR FIRST DEVICE?

7. o input & output devices
o multiple sensors
o several methods for
actuation and feedback
1 USER INTERFACE
#5 BEHIND THE SCENES – I/O

8. o mini-computers, micro-controllers
o run programs, analyze, calculate, do things no (normal) human understands
o control the sensors / actuator
#6 BEHIND THE SCENES – CONTROLLER

9. o Network hardware (Wifi, LAN,
Bluetooth, GSM, Zigbee, …)
o realize connection and
communication to servers,
input/output devices, other
things, clients, …
1 COMMUNICATION BACKBONE
#7 BEHIND THE SCENES – NETWORK

10. o prototyping helps ...
o … to know your users
o … to know the deployment
scenario
o possibility for quick and cheap
adjustments
o prototyping hardware
o Arduino
o Raspberry Pi
o BeagleBone
o Teensy
#8 PROTOTYPING IoT– POWER OF THE PROTOTYPE

11. o Wikipedia lists about 100 Arduino boards or
Arduino compatible boards/clones
o 5 million Raspberry PIs sold
o 3D printers will grow from a $288 million
market in 2012 to $5.7 billion in 2017
o DIY Drone community: 15,000 drones vs.
military forces: 7,000 “professional” drones
o By 2025, crowdfunding investment market
is projected to reach $93 billion
1 NICE TO KNOW FACTS
#9 PROTOTYPING / DIY – NUMBERS BESIDE THE GEEK STUFF

18. #14 HANDS ON – SKETCH

19. // the setup function runs once when you press reset or power
the board
void setup() {
// initialize digital pin 13 as an output.
pinMode(13, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
// turn the LED on (HIGH is the voltage level)
digitalWrite(13, HIGH);
// wait for a second
delay(1000);
// turn the LED off by making the voltage LOW
digitalWrite(13, LOW);
// wait for a second
delay(1000);
}
