Building Blocks of IoT

1. Building Blocks of IoT Hardware - Software - Cloud Amazon,Google, Oracle C IDE’s JavaScript ESP 8266 MicroPython Sensors Raspberry Pi Arduino Satish Rao

2. Building Blocks of IoT • Hardware • Sensors • Microcontroller vs MicroProcessor • Arduino vs ESP 8266 vs Raspberry Pi • Software • Programming Languages • Integrated Development Environments (IDE) • Cloud • Communication Protocols • Cloud Vendors

4. Sensors

5. Sensors used in Smart Home’s

6. MicroController (MCU) • Microcontroller is a processor that has its program and data memory built-in • Embedded inside some other device • Dedicated to one task • Low Power Devices • Small in size • Low in cost

7. Microprocessor (MPU) • Microprocessor is an IC which has only the CPU inside them i.e. only the processing powers such as Intel’s Pentium 1,2,3,4, core 2 duo, i3, i5 etc. • These microprocessors don’t have RAM, ROM, and other peripheral on the chip.

12. Why MCU for IOT ? • Simplicity • Simply turn them on, upload firmware, and they work. Additionally, the coding required to program an MCU is minimal • Low Power • Consumes Less Power and Power Saving mode can be enabled • No Operating System • Code on MCUs runs “bare metal”, meaning it includes no intermediary operating system to execute instructions • Cost •  Can deliver all the processing power and functionality one needs at Less Cost

13. Programming Languages and IDE’s • C/C++ • Most Popular Language for Embedded Systems • Mostly used for Arduino Boards • JavaScript • Widely used across Webpages • Popularity of Nodejs and open source nature • MicroPython • Optimized to run on microcontrollers

14. IDE’s • Arduino IDE • Arduino framework is built for makers, the simplest way possible. Firmware logic has two functions, setup() and loop() and is synchronous by design • Programming in C like Language • PlatformIO • Its an open source ecosystem forIoTdevelopment • Supports Arduino C • NodeRed • Flowbased programming for the IoT • Built on Nodejs

15. Cloud - Communication • Communication Protocols • HTTP • WebSockets • MQTT • CoAP

16. HTTP • Its most important protocol today • It gives embedded devices an opportunity to use any service that exists and uses a HTTP or protocol based on it. • Its simple to use with microcontrollers • Works on Request / Response principle

17. Websockets • WebSocket provides full-duplex communication • Connection is open between client and server • After initial handshake , each frame carries only a small header which reduces the overhead when compared to plain HTTP

18. MQTT • Stands for “Message Queuing Telemetry Transport” • Most popular M2M Protocols • Its lightweigh and simple to use • Uses Publish/Subscribe communication model

19. CoAP • stands for “Constrained Application Protocol” • It is a specialized web transfer protocol and ideal for use within constrained networks and environments • It’s built for multicast support, low overhead and simplicity. • CoAP is specifically designed to use minimal resources. This makes it ideal for the IoT. 

20. Cloud Vendors • Amazon • Microsoft Azure • Oracle • IBM Bluemix • ThingSpeak • Ubidots

21. Free IoT Dashboards • DIoTY - http://www.dioty.co • a cloud MQTT broker for the Internet of Things (IoT). • Easy to configure mobile app ready to use on both Android and iOS. • IoTtweet - http://www.iottweet.com/ • Free dashboard to control and record data from IoT. • Dweet.io – its like Twitter for “Things”

22. Programming Languages For IoT • C / C++ • Javascript • MicroPython • Python • Lua • Nodejs • Java • Ruby • Go • C# - Windows 10 IoT Core

23. Brains of IoT Raspberry Pi Arduino ESP 8266 C / C ++ Johnny Five JavaScript C / C++ Python JavaScript Nodejs Java Ruby/Go C# C / C++ MicroPython JavaScript Lua

24. Integrated Development Environment (IDE’s)

25. Arduino IDE Arduino framework is built for makers, the simplest way possible. Firmware logic has two functions, setup() and loop() and is synchronous by design.
