When you have a key-festooned unit called a MACROPAD, it’s only natural that one of the first things to try would be application hotkeys or macros. Press one of MACROPAD’s 12 keys to send a shortcut, function key or whole sequence of keystrokes to a connected computer. Turn the dial to select among different application sets.

Shake MatrixPortal to send off that nasty old 2020 and bring in a sparkly new 2021.

Some hints and tips for syncing up a Raspberry Pi with some of the very strangest display technology out there. Wide, skinny, round, hemispherical, projected by laser beams, worn on your head, sharks with laser beams attached to their heads…

CircuitPython and Google Spreadsheets can work together to make simple, personal IoT devices without server-side programming. Edit spreadsheet data in a web browser or mobile app — or collaborate with others on the same document — and have it appear on MagTag’s e-ink display.

Locally-grown foods are fun to explore and good for the community. But meal planning is more of a challenge as selections vary by location and season. MagTag will keep you in the loop!

For transit-bound people, the NextBus service is a tremendous convenience. Knowing when a bus is due means less standing out in the rain…one can use that time inside to get a little extra work done, or finish that cup of coffee. As a “heavy user,” I like having local routes always available at a glance…no need to even pull out a phone or click a bookmark, the information’s continually in view.

There’s something eye-catching about LED matrix graphics that you don’t get with a normal LCD display. This guide uses an Adafruit MatrixPortal M4 and RGB LED matrix to create an animated GIF player that’s drag-and-drop easy, like a pixelated version of a digital photo frame.

With RGB LED matrices, you might notice certain graphics appearing overly bright and washed out. This guide offers a couple techniques for preprocessing images to look better on these matrices.

Our electronic eyeball projects are an annual Halloween tradition. The Matrix Portal M4 board brings a retro-style return to form of our first eyeball project…but punching it up with bright colors, full-screen themes, and coded all in CircuitPython now.

Moon phases depicted on many wall calendars can be off by a day or more. Our Matrix Portal Moon phase clock lets you know where things stand right here and now!

We recognized the graphics one retail Halloween item — a bit of Adafruit open-source DNA in the wild! How deep does the resemblance go? We crack one open to see. It’s a lesson in bespoke electronics vs mass customization.

Adafruit Grand Central nudges in on what was previously the Raspberry Pi’s domain. Microcontrollers are getting beefy enough to handle images and video! Suitable for time lapse photography, small machine vision projects or just for fun.

This sequel to the RGBmatrixPanel library is more flexible and is easier to port to new devices. This guide has some tips for its use and development.

Using long exposure photographs, you can create beautiful light paintings with pixel art magically floating in mid-air using a strip of DotStar LEDs and Adafruit’s CLUE board running CircuitPython.
