The Twitterverse

Like it or not, Twitter is a force to be reckoned with. Millions of people use Twitter to talk about general happenings in the world and their lives. Large events like conventions, elections, and uprisings have a habit of crashing the Twitter servers.

You, an avid DIY hacker, want to know how to use that massive stream of digital social media. There are plenty of fun projects built around Tweeting something that happens. Today, we offer you an alternative: make something happen when a specific Tweet occurs.

This is a basic project that will walk you through the steps to get an LED flashing when a specific hashtag appears in the Twitter stream. While a blinking LED might not be the most exciting of outcomes, attaching Twitter to the physical world will get you started on creating that Twitter controlled robot.

A new kind of blinky!

We need to build a rather simple LED circuit to connect to the Raspberry Pi's GPIO header. Be sure you are familiar with LEDs and resistors.
