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)
