If you are just getting started with electronics, it can be difficult to know where to begin. With almost 2,500 guides published on the Adafruit Learning System, it might seem hard to figure out which guides are best for a beginner like you. Thankfully, we have each guide tagged with its difficulty level making it easier for beginners to find the right guides.
This is a square pixel display that uses an 32×32 RGB matrix display. It’s powered by the Feather RP2040 and RGB Matrix FeatherWing. This runs CircuitPython and the Matrix Portal Library to play animated sprite sheets on the display. The Feather RP2040 and RGB Matrix FeatherWing are mounted to a 3D printed frame on the back of the display. Paired with the FeatherWing Doubler, it’s easy to swap out the Feathers for future projects. A sheet of black LED acrylic fits over the display and diffuses the LEDs. The 3D printed grid fits over the PCB with each LED enclosed in a square. This separates each LED and blocks the light from leaking into each square.
ALS Deep Cut
With so many guides on the Adafruit Learning System, some amazing guides of years past get buried and lost. ALS Deep Cuts brings these guides back up to the surface. This week’s guide is from back in 2017.
Who doesn’t love a fat drum beat? Nobody, that’s who! You can make your own awesome rhythms once you’ve built the FruitBox Sequencer! Use the Circuit Playground Express board’s built-in capacitive touch sensors plugged into pieces of fruit to program and trigger your beats, in a 16-step sequence. Play back sampled drum sounds in perfect time with the on-board speaker, or optionally, you can plug it into an amplified speaker to rock the crowd!
The Collin’s Lab series covers a variety of topics within the realms of electronics and technology as a whole. Most of the episode topics were based on whatever I was interested in at the time. I’ve always enjoyed this sort of teaching-while-learning process, as it clearly highlights the novel & surprising facts, and helps to avoid the pitfalls of factual regurgitation.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
