Our range of LED dot matrix displays are used for all sorts purposes, and one new example we'd like to share is by Mark Cohen who uses the DMD to display RSS news feeds of interest. The process is quite simple, and requires a PC running ruby code to extract the required RSS feed and send it as text to the serial/USB ouput.
The Arduino-compatible board then receives the text stream via USB and sends it to the DMD. A quick demonstration is shown in the following video:
This is a great example of using a DMD to display relevant information - many websites, services and even cloud-based email providers can offer an RSS feed which you can now harness for the DMD. You could also use two or more DMDs for a longer display!
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.
