Petduino Matrix Designer

Published: 18 October 2015

For anyone who has played with a Petduino, you'll know that the 8x8 matrix is updated using a binary or hex formatted byte array to represent the image you want to render. Whilst editing 1's and 0's in a binary array isn't that hard, it can be a little tricky to really "see" the image you are trying to create.

To help with this I've put together a little matrix designer web app which lets you click on LED's to turn them on and off, and which automatically converts the visual design into both binary and hex formated arrays usable by the Petduino library.

Hopefully this will make creating graphics and animations on the Petduino just a little bit easier.

Head on over to to check it out.
