As part of his thesis for a Masters degree, Marcelo Vicente has created a DECT wireless communication shield for Arduino. The DECT (short for DIgital Enhanced Cordless Telecommunications) standard is normally used for wireless home phone however with Marcelo's shield your Arduino can transmit audio wirelessly to remote DECT devices, experiment with telephony and increase your knowledge about the DECT standards.
Furthermore Marcelo has published the design details and Arduino detail as well so you can reproduce your own. So to get started visit the DECT shield page. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you'd like to learn about Arduino - but not sure how to start - then the best way to learn is with our Experimenter's Kit for Arduino:
The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects!
So to get started or for more information and to order, check out the product page.
