Logging data from a variety of sources is a great use for the Arduino platform, however the majority of solutions tend to write the data to a memory card for retrieval at a later date. However various solutions to real-time remote data access are appearing, and one example is provided by Chuck Bell with his MySQL connector for Arduino. Although still in beta stage, the connector allows any Ethernet-enabled Arduino board to not only store data from your project to the MySQL server but also retrieve values stored in the server to the Arduino.
Example sketches are provided which demonstrate how to get lookup values, process resultin sets, with which you can easily work with and expand. This type of project really enhances the possibilties of Arduino-based projects, so visit Chuck's website to learn more and download the required library. 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.
