Year of the Goat Munich - Simon Mang - SixReasons - Hardware prototyping – Sketching with hardware

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

12. EXAMPLES – AND COOL STUFF YOU CAN DO WITH ARDUINO & CO.

13. #10 EXAMPLES – BLOWFISH

14. #11 EXAMPLES – DIY DRONES

15. #12 EXAMPLES – MY IoT

16. HANDS ON
o Blink example (LED)
o Switch example (LED + Switch)
o Controller example (LED + Poti)

17. #13 HANDS ON – BLINK

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);
}
#15 HANDS ON – CODE

20. #16 HANDS ON – SWITCH

21. #17 HANDS ON – SKETCH

22. // the setup function runs once when you press reset or power
the board
void setup() {
//...
// initialize the pushbutton pin as an input:
pinMode(2, INPUT);
}
// the loop function runs over and over again forever
void loop() {
// read the state [0;1] of the pushbutton value:
buttonState = digitalRead(buttonPin);
// check if the pushbutton is pressed.
// if it is, the buttonState is HIGH:
if(buttonState == HIGH){
//... see blink example
}
}
#18 HANDS ON – CODE

23. #19 HANDS ON – POTI

24. #20 HANDS ON – SKETCH

25. // the setup function runs once when you press reset or power
the board
void setup() {
//...
}
// the loop function runs over and over again forever
void loop() {
// ...
if(buttonState == HIGH){
// read the value from the sensor [0-1023]
timeout = analogRead(A0)
// ...
}
}
#21 HANDS ON – CODE

26. o Questions?
o Feedback?
o Ideas (what I could do next
weekend)?
#22 THE END – NETWORKING DRINKS AHEAD!
