Build a giant countdown timer with Arduino

Our LED matrix DMD display boards have found a home in many applications, and another useful example has been documented by Darren yates from APCmag in Australia. This project uses the DMD as a display board for a neat countodown timer, which could be used to count up or down in seconds and minutes - and then sound an alarm at the end of the period.

Of course you could modify this with all sorts of options to meet your requirement - the Arduino "sketch" to control a DMD is very simple and also described in our tutorial. After a short period you will get an understanding of how to control the screens and use them in your own applications.

For more information about Darren's timer project - visit the APCmag website and their magazine. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well. 

As used in the project mentioned above, check out our Freetronics Dot Matrix Displays. They're simple to use, yet very bright for indoor and outdoor situations. Available in various colours, the 32 x 16 LED matrix can display text and graphics quite easily - and can be daisy-chained together for extended displays.
