- 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)
