At Adafruit, we’re committed to helping you improve your knowledge and skills, and providing you with the resources to make your projects awesome. We did some research and came up with a comprehensive compendium of diffusion materials, from paper to plastic to foam and more. We test specialty LED diffusion products and compare them to inexpensive household items to give you a guide on which material will give you the LED pixel look you want for your project or artwork.
From the guide:
NeoPixel and other addressable LED strips are a lot of fun to use, and there are so many possibilities and ways to make beautiful things. Pixels are gorgeous on their own, but when they diffuse into or reflect from other objects, they become pure magic.
Adafruit engineers and artists have brought together some of our experience and knowledge about diffusion materials and techniques. We’ve tested some common materials, as well as special materials and fun things we’ve found and loved, in the hope that you’ll be inspired and accelerate your journey of making beautiful things with electronics.

Stop breadboarding and soldering – start building now! Adafruit’s circuit playground is filled with LEDs, sensors, buttons, alligator clip pads, and more. Build projects in minutes with Circuit Playground through the drag-and-drop MakeCode programming site, learn computer science with CS Discoveries courses on code.org, jump into CircuitPython to learn Python and hardware, TinyGO, and even use the Arduino IDE. Circuit Playground Express is the latest and greatest Circuit Playground board, supporting CircuitPython, MakeCode and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, infrared reception and transmission, two buttons, a switch, 14 alligator clip pads and a large number of sensors: capacitive touch, infrared proximity, temperature, light, Movement and sound. A vast world of electronics and coding awaits you, and it’s right in the palm of your hand.
