Once again Australian enthusiast Beau Walker has created a functional and interesting product based on a Freetronics EtherTen and some simple external circuitry. In this example Beau has made a clock with retrieves the time using the network time protocol, and displays it using 7-segment LED digits driven by the MAX7219 LED display driver IC. A clock like this is great for solving common household arguments about what the correct time should be and is also a great exercise in Arduino, Ethernet and prototyping. Furthermore the decimal point LEDs have been used to indicate AM/PM and display the connection heartbeat:
Very well done - and for more details and notes, visit Beau's website. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
