This is a simple touch-enabled, light up tone piano. This guide allows you to use PyLeap to send code and any necessary libraries directly to your Circuit Playground Bluefruit.

The Adafruit VL53L1X is a Time of Flight distance sensor that has a massive 4 meter range and LIDAR-like precision. The sensor contains a very tiny invisible laser source and a matching sensor. The VL53L1X can detect the "time of flight", or how long the light has taken to bounce back to the sensor.

These breakouts are three in one: an ATtinyxxx development board, a seesaw board, and a STEMMA QT I2C controller or peripheral! This mini development board lets you design with ATtinyxxx, or acts as a little I2C-controlled friend to do all the timing-sensitive things many microcontrollers and microcomputers are not good at.

You already have Git setup, and you have a GitHub account. You want to contribute to an open source project like the Adafruit Learning System, but you're not sure where to start. This guide walks through the steps from forking your first repo to your GitHub account, to cloning it locally, creating a working branch, making a commit, pushing your code to your fork, creating a PR, and both receiving and giving a review. You'll learn good practices and tips and tricks.

Have you always wanted to upgrade your ensemble with a creepy-cool creature PCB silkscreen and an eye-blistering arrangement of LEDs? The Adafruit EyeLights LED Glasses have you covered with 116 artfully arranged 2x2mm RGB LEDs, all controlled with an IS31FL3741 I2C Driver that handles all the PWMing, so it's plug-and-play with the Adafruit EyeLights LED Glasses Driver board.

This funky user interface element is reminiscent of the original clicking scroll wheel interface on the first iPods. It's a fancy mechanical kit but has an intuitiveness that is hard to argue with - everyone knows how to use this kind of rotary encoder to scroll and select.

It's half USB Key, half Adafruit Trinket M0, half APDS9960 breakout...it's Proximity Trinkey, the circuit board with a Trinket M0 heart, APDS9960 Proximity, Light, RGB, and Gesture Sensor, and two RGB NeoPixels for a customizable glow. Now it's super easy to add one of the most popular combination-sensors to any computer with a USB port. You'll be ready to go in an instant!

Add a splash of RGB LEDs to your project, via STEMMA QT! The ISSI IS32FL3741 communicates over I2C and can set each LED element with 8 bit PWM for 24-bit color across the RGB elements, for beautiful color! There's an adjustable current driver so you can brighten or dim the whole display without losing color resolution.

CircuitPython supports MP3 playback, and as MP3s are smaller than wav files, it's a perfect match for your RP2040 microcontroller board! Learn how to play MP3s using a board with a built in speaker, and using a Pico with a speaker wired up.

The SCD-40 and SCD-41 are photoacoustic 'true' CO2 sensors that will tell you the CO2 PPM (parts-per-million) composition of ambient air. They really are measuring the CO2 concentration! Perfect for environmental sensing, scientific experiments, air quality and ventilation studies, and more.

The Adafruit MCP9601 I2C Thermocouple Breakout (a.k.a MCP96L01) is an excellent amplifier with a cold-compensation reference, all over I2C. The chip can interface with just about any thermocouple type, as well as being able to set various alerts for over/under temperature.

For those who like to forge their own path, we now present the easiest way of creating custom ortholinear key matrices. Instead of hand soldering together a custom matrix of NeoKey socket breakouts, the Adafruit NeoKey 5x6 Ortho Snap-Apart Mechanical Key Switches with NeoPixel has 30 key switches that can be snapped apart to make any size grid.

These keycaps are 3D printed with the braille alphabet so folks can touch and feel their keyboard shortcuts. The project also has audible feedback so a tone is played when a key is pressed.

Those who have experimented with hot-plugging I2C devices eventually have discovered that if you plug in or unplug at the wrong moment you can cause the bus to hang. The Adafruit TCA4307 Hot-Swap I2C Buffer breakout solves that problem.

Get ready to upgrade your desk's mission control station with a CircuitPython or Arduino powered Macropad - complete with 12 buttons, OLED display, speaker and rotary encoder. Customize it for your spacecraft to help guide you through the great reaches of the unknown.
