This guide will show you how to add an IR receiver to a Teensy 3.1 to play patterns on a 32×32 Pixel RGB LED Matrix Panel. The Teensy 3.1 runs an Arduino sketch that draws to the display, listens for IR remote commands, and refreshes the display at a high frame rate with good color depth. The SmartMatrix Shield makes it easy to connect everything together.
This guide can be used in combination with the SmartMatrix Animated GIF Player guide. Adding a microSD card adds support for playing animated GIF files in addition to patterns in the Arduino Sketch.
We will explain the basic soldering and wiring to connect the IR receiver to the SmartMatrix Shield, and how to load the Arduino sketch that controls everything onto the Teensy 3.1….
