Control a motorised food dispenser with twitter

Although twitter can be used for disseminating everything between mindless gossip touseful news, it also makes an interesting conduit for remotely controlling an Arduino. How? Using a very simple sketch you can have an Internet-connected Arduino board use the twitter search engine to look for a particular hashtag (e.g. #arduino). Upon returning a result the Arduino can then take action. This is exactly what Gregory Fenton has done, however for his example when someone mentions a certain hashtag, his electronic sweets dispenser is activated – thus handing out a treat.

It’s a fun application that can be altered for various purposes, so click here for more information. And for more, we’re on twitter and Google+, so follow us for news and product updates as well.

When putting together your next Internet-enabled Arduino project – save time, space and money with the Freetronics EtherTen. Apart from being fully Arduino Uno-compatible, it has onboard Ethernet, microSD socket, full USB interface (so you don’t need a costly FTDI cable just to upload a sketch!) and supports optional Power-over-Ethernet.
