Real-time Graphing with Raspberry Pi and Plotly #piday #raspberrypi @Raspberry_Pi

From instructables user plotlygraphs:

Time for some Raspberry Pi + Plotly Streaming fun!

Recently we completed an Instructable for visualizing temperature and humidity data using an Arduino and Plot.ly, a free online collaborative graphing tool. Now it’s time to extend that fun to all Raspberry Pi users!

The Raspberry Pi is a fantastic platform for software experimentation, allowing kids, amateurs and professionals alike to hack away without fear of breaking an expensive computer system. I’m a huge fan, and have done a few projects with my Raspberry Pi, from setting up a web server in our workshop, to using it as a desktop PC when my laptop was in the shop.

Raspberry Pi fun isn’t limited only to software activities though! In addition to its other great features, the Raspberry Pi has some GPIO (General Purpose IN/OUT) pins, which you can use to read data from!

The purpose of this Instructable is to take some temperature data read from a TMP36 sensor, and visualize it using real-time streaming using the Plotly Python API!

Here is an example of our final product: https://plot.ly/~demos/1415/

See the full instructable or take a look at another Plotly project

Adafruit Assembled Pi Cobbler Breakout + Cable for Raspberry Pi – Model B: Now that you’ve finally got your hands on a Raspberry Pi® Model B , you’re probably itching to make some fun embedded computer projects with it. What you need is an add on prototyping Pi Cobbler from Adafruit, which can break out all those tasty power, GPIO, I2C and SPI pins from the 26 pin header onto a solderless breadboard. This set will make “cobbling together” prototypes with the Pi super easy. Designed for use with Raspberry Pi Model B AND Model A, both revisions. This will not work with the Raspberry Pi 2 or Model A+ or B+ If you have one of those, check out our 40-pin version of this item. (read more)
