README.md

A small application to drive LED matrix displays, such as the pimoroni unicorn, from nodejs. My intention is to create a digital graffiti/guestbook system.

Make sure you are on a recent nodejs version. Raspbian has an old version. Use nodesource ;).

Copy config.example.json to config.json and pick a driver + display size.

execute:

npm install
nodejs pixdisp.js

Navigate to http://localhost:8080/

Matrix driver & Unicorn Hat HD driver inspired by https://github.com/vesteraas/node-unicornhathd

Drawing

Device drawing

Simple clicking on the canvas in the responsive webinterface makes things light up.

Camera

Using your camera

The webinterface allows you to capture your camera and submit images from there.

Webinterface

Web interface

A simple web interface is included for drawing on the device. Defaults to port 8080.
