Displaying Images on the Freetronics DMD LED Display with Node.js

Displaying Images on the Freetronics DMD LED Display with Node.js

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.

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.
