Internet Of Things
Why ?
Why IOT
- We humans are lazy and intelligent.
- If you want to scale things automation is must.
- Better decision making.
- New business models.
- Very less chance of errors.
Automation For Scaling
And It's So Cool = Read This : Link
Decision making
"There's data everywhere"
"Data helps in decision making"
Decision making
Everything has a state which is represented by attributes
Expiry Date
Heart Rate
Age
Time
Decision making
States of objects can/be changed and the record of all the state changes over the time period is data
Decision making
location information
health monitoring
Home appliances monitoring
Traffic monitoring & Control
Waste tracking & management
Access Control & Security

Let's define a "T" from "IOT"
Thing -
The definition of a “Thing” in the Internet of Things varies a lot. We will define a Thing as an embedded computing device (or embedded system) that transmits and receives information over a network.
Now, let's select a hardware platform for prototyping the "T(Thing)"
Options are
- Arduino (E.g. Uno, Intel Edison)
- Raspberry Pi
- BeagleBone Black
- Ti Launchpad
- ESP8266 and many more....
Arduino Uno
Raspberry Pi
Beagle Bone Black
Ti Launchpad
Arduino
- It's a MicroController
- An open-source physical computing platform based on a simple MicroController board
- Takes input from sensors and creates output depending on how you code it
- So many versions (Uno, Leonardo, mega...)
- Most famous DIY board
- LINK
Raspberry Pi
- It's a complete Computer.
- Has Operating System
- More powerful than Arduino
- Cheap $35
- Very famous in DIY community
- Easy to learn as it runs all kinds of Operating systems
- LINK
BeagleBone Black
- It's a complete Computer.
- Has Operating System
- More powerful than Raspberry Pi
- Very famous in DIY community
- Easy to learn as it runs all kinds of Operating systems
- More expandable
- More no of GPIO pins
- Realtime processing using PRUs
- My Favourite
- LINK
Ti Launchpad
- It's a MicroController
- An open-source physical computing platform based on a simple MicroController board
- Takes input from sensors and creates output depending on how you code it
- Similar to Arduino
- Used in MitEdx "intro to embedded systems" course
- LINK
I Choose Arduino
- Easy to learn.
- Widely Available in the market
- Cheap ₹600 - ₹800 (Indian Makes)
- So many versions (Uno, Leonardo, mega...)
- Most famous DIY board
- Wide community support
- Awesome minimal IDE
What's on board
The Arduino IDE
-
Plug your Arduino into USB port
- Select your board and correct port in IDE
Process
Board Selection
Port Selection
Example Selection
Hello World (Blink)
Connect led long leg(+) to pin 13 of Arduino
and short leg (-) to GND pin
Click the verify button then click the upload button
Success
Cool Eh!!
Now ?
build an "I" from "IOT" ?
Nahh !!!!
it's already there to serve us

Arduino Shields
Shields are boards that can be plugged on top of the Arduino PCB extending its capabilities. The different shields follow the same philosophy as the original toolkit: they are easy to mount, and cheap to produce.
Ethernet Shield
Wifi Shield
GSM Shield
CC3000
ESP8266
