There are many uses for our large DMD Dot Matrix Displays, and we’re always excited to see new ways of interfacing with and controlling these super-bright display units. An excellent example of this has been demonstrated by Patrick Catanzariti who shows how easy it is to control a DMD with an Arduino and Node.js on a host PC.
The combination of Arduino and Node.js is used to decode a .png image file, and send the image data to the display. As you can see from the image below you can convert any image with a size of 32 x 16 pixels, and thanks to Patrick’s code you can recreate this yourself.
Furthermore the article includes a neat explanation of how the DMDs are controlled with the Arduino sketch so you will have a mastery of the subject in no time at all – so click here to get started. And for more, we’re on facebook, Google+, and twitter – so follow us for news and product updates as well.
If you would like to have fun with node.js and a large LED dot matrix display – check out the 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.
