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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
