  • 34. Open Hardware• What is Open Hardware
  • 35. Open Hardware• What is Open Hardware? – Free – Open Source Software (not free hardware!) – Open schematics – build instructions – Mostly found as : • Microcontrollers • Linux boards
  • 36. Open Hardware• Arduino – No special introduction needed! – Microcontroller platforms – Great community support – A lot of apps + extensions
  • 37. Open Hardware• Arduino – Communication – Ethernet – WiFi – GPRS – Through Android - Computer
  • 38. Open Hardware• Arduino – Communication – Integrated solution • The Nanode
  • 39. Open Hardware• RaspberryPi – Linux board – Ethernet – USB in, HDMI output – 700MHz ARM, 256 RAM, GPU – 35 £
  • 40. Open Hardware• RaspberryPi• Sensors communication – GPIO• Internet communication – Ethernet – C/C++, Java, Python, QT, …
  • 41. Communication Protocols– HTTP– WebSockets– CoAP– MQTT– ….
  • 42. Communication Protocols– HTTP • REST Web Services • Simply just HTTP POST/GET Request: • Nimbits:http://nimbits1.appspot.com/service/currentvalue? value=23&point=Temperature&email=arduino.sensors.cloud@g mail.com&format=double&secret=0a6f15d6-bc57-4de7- be41-77263f4b3f6d
  • 43. Communication Protocols– HTTP • REST Web Services • Arduino code:client.println("GET /service/currentvalue?value=" + s + "&point=test&email=&format=double&secret=xxx HTTP/1.1");client.println("Host:nimbits1.appspot.com");client.println();client.stop();
  • 44. Communication Protocols– HTTP • Is it suitable for Cloud and devices interaction?
  • 45. Communication Protocols – HTTP • Is it suitable for Cloud and devices interaction?• Overhead• Delays• Server overhead
  • 46. Communication Protocols– WebSockets– New concept for real time message exchange over the Web– Open Server Session
  • 47. Communication Protocols – WebSockets• API for Browsers (JavaScript)• Libraries for Java, PHP, Ruby …
  • 48. Communication Protocols– WebSockets– Arduino library exists already!– Services that use WebSockets • Pusher • http://websocket.org/echo.html
  • 49. Communication Protocols– Constrained Application Protocol (CoAP)– Based on HTTP principles • RESTful communication • BUT: UDP protocol– Supports multicast(-) Needs special ports open (5683 not 80/8080)Still Draft protocol
  • 50. Communication Protocols– Message Queue Telemetry Transport (MQTT)– Machine 2 Machine– Publish / Subscribe Model– Already used by applications • Facebook messenger (iPhone/Android)– Open protocol– You need special software server– There is an Arduino library available!
  • 51. Examples• Anything that can be connected to the Arduino – Sensors – Control (relay) switches• Cloud -> – Manage / Visualize data – Remote Control
  • 52. Examples• Ideas for some Projects … – Read barcodes + Send information on the Cloud (Cloud-based shopping list) – Control power consumption (openenergymonitor.org) – Web home automation (smart home)
