Getting started with the Internet of Things

What is IoT?

An extension of the traditional web

providing intelligent features

through embedded computing,

which allows dumb objects

to autonomously react, inform and learn

from the context of Humans and Things

Tom Collins@snillocmot

How is IoT?

The convergence of

cheaper and accessible

cloud, network and processing power,

with smaller and smarter computers

and a variety of hardware I/O sources

Where is IoT?

Where is IoT?

Where is IoT?

By 2020...$7.1 trillion market value

50 billion connected devices

30 million every day

1 in 3 ‘knowledge workers’ will be

replaced by a digital workforce and smart machines

Why IoT?

To improve quality of life and drive new business

through connecting physical, cyber and social domains

Connected devices

Problems

● Millions of apps● Still stuck in remote control mode● Siloed solutions (An API doesn’t make it IoT)● Big innovation captures the consumers eye,

but not enough immediate ROI for business to adopt

SmartLivingIoT Starter KitA Computer (Arduino Ethernet, Intel Edison or Raspberry PI) & Grove shield

Arduino - setupvoid setup(){ pinMode(ledPin, OUTPUT); // initialize the digital pin as an output. Serial.begin(9600); // init serial link for debugging byte mac[] = {0x90, 0xA2, 0xDA, 0x0D, 0xE1, 0x3E}; // Adapt to your Arduino MAC Address

if (Ethernet.begin(mac) == 0) // Initialize the Ethernet connection: { Serial.println(F("DHCP failed,end")); while(true); //we failed to connect, halt execution here. }

delay(1000); //give the Ethernet shield a second to initialize: if(Device.Connect(&ethClient, httpServer)) //connect the device with the IOT platform. {

Arduino - sensor read loopvoid loop(){ unsigned long curTime = millis(); if (curTime > (time + 1000)) // publish light reading every 5 seconds to sensor 1 { unsigned int lightRead = analogRead(knobPin); // read from light sensor (photocell) if(prevVal != lightRead){

Arduino - actuator callbackvoid callback(char* topic, byte* payload, unsigned int length) { String msgString; {

Rules

FYI● Rule wizard doesn’t support complex operators like &&, ||● Create a script and run it in the cloud if you need crazy logic

Hackathon Ethos

Fake it, until you make it (literally)

● Hackathons always have network issues

● Hardware is normally limited or even shared

● Mock data is easy● Things always go wrong● Fancy UI elements always look

good

KISS, Hardware is Hard, Retrofit

● Nest is just a potentiometer, temp, PIR sensor

● GNL is just a LED & Push Button● Hue is just a RGB● Wemo is just a Relay

MVP Mentality

● Build small think big (What’s the story behind your use case)

● High impact features first

Brainstorming IoT

The problem - Short sharp sentence describing the story of your problem and how the solution solves it

Topology diagram - Visualise what you’re going to build, show the inputs and outputs and use it to explain your idea

THINGS - What are the dumb objects?

END POINTS - What computers and sensors are need to make things smarter?

DATA MODEL - What type of data will the Things produce? What are the inputs/outputs?

MIDDLEWARE - How will devices communicate? one-one, one-many?

AUTOMATION - When this event happens then do this event?

UI - Mockups and wireframes

HUMANS - Who are the most important people using the solution?
