Matrix Painter – Draw using your phone!

Awesome tutorial video from engineerish on YouTube! Description and details from GitHub:

The “Matrix Painter” is a project where you control 8×8 LED Matrices from either your computer, a friends computer, or any other device such as a phone.

Processing

An app written in Processing (read more about Processing here) connects to the Arduino via the Serial port.

Note to Windows users: This project was developed on a Mac – you’ll need to poke around in the serial port string in order to find the right one

The app has a UI for controlling the pixels on the matrices.

The app also opens a TCP server on port 5204 which allows for further ways of controlling the matrices by connecting clients.

iOS

In the project there’s a simple iOS app that renders a grid, representing the matrices. The app connects to the TCP server running in the Processing app.

In order to compile the iOS project you’ll need Xcode.
