One Thousand~ Pixels

Workshop at Master of Arts in Interaction Design, Mendrisio 9–13 January 2023

Project Brief

The aim of the workshop is to embrace constratints and develop ideas around limits. Develop and idea and a working prototype using a 32×32 RGB LED matrix.

Topics

  • Idea driven development and research
  • Realtime graphics and animation concepts
  • Serial communication
  • Quick prototyping

Part list

  • RGB LED matrix 32x32 P6 (P6 means that the LED pitch is 6mm)
  • HUB75 ribbon cable (usually comes with the matrix)
  • 5V power cable for the LED matrix (usually comes with the matrix)
  • 5V power supply (3A minimum), plus cables
  • Teensy 4.0 or 4.1 development board (a Teensy 3.2 will do but has limited memory)
  • SmartMatrix shield (not strictly necessary but handy to quickly connect the microcontroller)
  • Micro-USB cable

Software requirements

Examples

All the examples rely on the SmartMatrix library for Arduino. The many features of the library are not demonstrated: the libraray comes with an extensive collection of examples.
