There are many ways of messaging the outside world from your Arduino, and one method is using the popular microblogging service twitter. Although doing so may seem complex, nothing could be further from the truth - and by following the latest tutorial on the tronixstuff website your Arduino will be tweeting in no time. Unlike other methods this tutorial doesn't rely on a connection to a third-party platform or using an external computer - the Arduino sketch and Ethernet hardware can take care of the lot.
Apart from sending simple text messages to twitter you can also send data created by a sketch or gathered from sensors, allowing you to create intelligent alarm and alert systems. So to get started, head over to the tutorial page. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're looking for an Ethernet-enabled Arduino board with plenty of I/O or if your projects outgrow the normal Arduino-compatible boards, running out of program and flash memory space, or you're stacking on Ethernet and microSD shields, or all at once - it's time to upgrade to the Freetronics EtherMega:
Quite simple the EtherMega is the fully-loaded Arduino-compatible board on the market today. Apart from being completely Arduino Mega2560-compatible, it includes full Ethernet interface, a microSD card socket, full USB interface, optional Power-over-Ethernet support and still has a circuit prototyping area with extra I2C interface pins. So if your project is breaking the limits, upgrade to the EtherMega today.
