10. Twitter-controlled Mood Lamp

Massimo Banzi is back for the final Arduino video tutorial, and this time, he will be using a Wi-Fi shield module to connect his Arduino unit to the Internet. This obviously opens up a whole range of new possibilities, which Banzi explores in the video.

For the purposes of this demonstration, Banzi creates a simple lamp circuit that will change colour according to the messages posted on Twitter. So if someone, for instance, Tweets a message that begins with #ArduinoRGB followed by a colour represented by a six digit decimal number (like the way colours are displayed in HTML), the lamp will then change colour accordingly.

So to see how this clever device works, make sure that you tune in to the final video.
