Use a RasPI and an RGB LED To See The Colors of Twitter In Real Time @Raspberry_pi #piday #raspberrypi
Whiskeytangohotel posted a tutorial for a recent project involving a raspberry pi, rgb led, and twitter. While many projects with pis incorporate twitter, we think this one stands out for its simplicity:
This project uses a Raspberry PI to scan all posted Tweets in real time for the mention of a color. When a color is Tweeted the Red, Green, and/or Blue segments of a RGB LED are turned on to display the Tweeted color.
The project is pretty cool and simple to duplicate. You should be able to just copy/past my Python script below into your favorite RasPI editor and go from there.
Note that the code expects the RGB LED to be connected to I/O Pins 11 (Red), 15 (Green) and 13 (Blue). Also, be sure to add a current limiting resistor to each of the three I/O pins; not the RGB LED ground pin. My RGB LED was spec’d for 330 Ohm resistors. This picture should help identify Pins 11, 15, and 13:
You will also need to establish your own Twitter API Token. Don’t worry; it’s easy if you already have a Twitter account. To get them go to https://dev.twitter.com/. Enter these API Token values where the X’s are in the source code below…
