Chart data into the cloud with the ThingSpeak service. ThingSpeak is a site which allow posting, displaying of data. This service allows an easy gateway to MRL data to be sent and displayed there. Any data producing service (Arduino, OpenCV, Runtime, etc) can send messages to the ThingSpeak service and it will relay the data to a user defined channel.
The following Python script will start and Arduino and ThingSpeak service. It will then subscribe the ThingSpeak service to listen to the Arduino's publishPin event, and relay the data to a users public channel. The data can be viewed here at the moment : https://www.thingspeak.com/channels/4050
Analog data being traced on pin 15 (A1) - The data is relayed to ThingSpeak
Seems like there is a lot of potential here to do fun things.
