LED Pixel Hoops

Build an LED scoreboard with mini IR sensing hoop using an RGB Matrix and CircuitPython! This indoor game lets you shoot hoops and display your score on a 64x32 LED Matrix.

IR Sensing Hoop

The hoop houses an IR breakbeam sensor that detects when a ball has gone through it. The 3D printed parts hold everything together and are designed to be easy to build. There’s an arcade button on the side that’s used for starting a new game and resetting the score. This build is powered by an Adafruit Feather M4 Express and the RGB matrix FeatherWing.

Prerequisite Guides

Take a moment to walk through the following guides to get better understanding of the parts used in this project.

Black LED acrylic is used to diffuse the LEDs that are otherwise harsh and over exposed. This material features a matte finish and has the ability to transmit any color of light. That makes it perfect for bringing out the vibrance in the colors of the LEDs.

The 3D printed frame is designed with a slot on the side so it’s easy to insert a sheet of Black LED acrylic.
