An unpainted art canvas can make a great diffusion screen for RGB matrix panels. In this guide I’ll show how to use art canvases to construct wall-hanging matrix panel enclosures for several different sizes of RGB matrix panels.
This guide will help you to build one of these wall-hanging canvas displays.
ALS Deep Cut
The Adafruit Learning System has now 2,335 published guides! As you can imagine, some amazing guides of years past get buried and lost. ALS Deep Cuts brings these guides back up to the surface.
From the moment theseLEDdisplays made an appearance on our weekly Ask an Engineer show, comparisons were being made to the DeLorean time circuit from the Back to the Future films. It was a moral imperative then to make a demo! If you’re handy with Arduino and some shop tools, you should be able to pull off something similar (better, even), or adapt the ideas to other projects. This was quickly built in fun, so please don’t expect the same level of polish as a finished product tutorial.
The Adafruit MagTag combines the new ESP32-S2 wireless module and a 2.9″ grayscale E-Ink display to make a low-power IoT display that can show data on its screen even when power is removed! The ESP32-S2 is great because it builds on the years of code and support for the ESP32 and also adds native USB support so you can use this board with Arduino or CircuitPython!
This OLED goes out to all the fans who want more pixels! Normally our 128×64 OLEDs are the biggest ones we’ve stocked that can use I2C. This one is a whopping 128×128 pixels and it even has an extra bonus – it can do grayscale pixels! Yep, you get the same crispness of a monochrome OLED but with 16 levels of gray.

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.
