#AdafruitLearnSystem Weekly Update: More Pico!

Since my last update, there were a 19 new guides published to the Adafruit Learning System! There were 4 new product guides, a milk freshness checker using a digital nose (yea, you read that right), many new Raspberry Pi Pico projects, a new MagTag project for sports fans, and more!

Favorite New Guide

Take off and soar with these animatronic cosplay wings. The 3d printed back plate holds metal gear servos which are strong enough to support light to medium weight wings, and the lipoly battery will keep them flapping for hours.

You can attach store bought wings, or create your own unique fairy wings from cellophane and poster board or Bristol board. Make flapping dragon wings, or angel wings, or leathery bat wings if you like. The sky is the limit.

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.

Kaleidoscope Eyes (Trinket-Powered NeoPixel LED Ring Goggles)

Here’s a project to dazzle onlookers at Halloween parties, cosplay conventions, raves or at Burning Man. These full-color animated LED goggles attract a LOT of attention!

Adafruit NeoPixel LED rings fit perfectly inside the eyecups of most 50mm round goggles — a very common size. It’s almost as if these rings were made with this project in mind!

New Product Guides This Week

This week Adafruit published six new product guides!

Adafruit SCD-30 – NDIR CO2 Temperature and Humidity Sensor

Take a deep breath in…now slowly breathe out. Mmm isn’t it wonderful? All that air around us, which we bring into our lungs, extract oxygen from and then breathe out carbon dioxide. CO2 is essential for life on this planet we call Earth – us and plants take turns using and emitting CO2 in an elegant symbiosis. But it’s important to keep that CO2 balanced – you don’t want too much around, not good for humans and not good for our planet.

Adafruit 1.54″ eInk Display Breakouts

Easy e-paper finally comes to microcontrollers, with these breakouts, shields and friends that are designed to make it a breeze to add a tri-color eInk display. Chances are you’ve seen one of those new-fangled ‘e-readers’ like the Kindle or Nook. They have gigantic electronic paper ‘static’ displays – that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!

We’ve liked these displays for a long time, but they were never designed for makers to use. Finally, we decided to make our own!

Adafruit Circuit Playground Tri-Color E-Ink Gizmo

Extend and expand your Circuit Playground projects with a bolt on E-Ink Gizmo that lets you add a lovely tri-color e-Ink display in a sturdy and reliable fashion. This PCB looks just like a round E-Ink breakout but has permanently affixed M3 standoffs that act as mechanical and electrical connections.

What is e-Ink? Chances are you’ve seen one of those new-fangled ‘e-readers’ like the Kindle or Nook. They have gigantic electronic paper ‘static’ displays – that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!

Adafruit BMP388 and BMP390 – Precision Barometric Pressure and Altimeter

Bosch has been a leader in barometric pressure sensors, from the BMP085. BMP180, and BMP280… now we’ve got the next generation, the Adafruit BMP388 and BMP390 Precision Barometric Pressure sensors. As you would expect, this sensor is similar to its earlier versions but even better. The BMP3xx has better precision than the BMP2xx series which makes it excellent for environmental sensing or as a precision altimeter. It can even be used in either I2C and SPI configurations.

The BMP3xx is the next-generation of sensors from Bosch, and is the upgrade to the BMP280 – with a low altitude noise as low as 0.1m and the same fast conversion time. And like the previous BMP280, you can use I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.

Getting Started with Raspberry Pi Pico and CircuitPython

The Raspberry Pi foundation changed single-board computing when they released the Raspberry Pi computer, now they’re ready to do the same for microcontrollers with the release of the brand new Raspberry Pi Pico. This low-cost microcontroller board features a powerful new chip, the RP2040, and all the fixin’s to get started with embedded electronics projects at a stress-free price.

Introducing Adafruit Feather RP2040

A new chip means a new Feather, and the Raspberry Pi RP2040 is no exception. When we saw this chip we thought “this chip is going to be awesome when we give it the Feather Treatment” and so we did! This Feather features the RP2040, and all niceties you know and love about Feather


8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!

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.
