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….

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
