This sensor contains a thermistor temperature sensor and a capacitive humidity sensor. A small microcontroller inside does the readings and provides a simple I2C interface for reading the finished & calibrated output data. This guide will cover how to use this sensor, complete with wiring diagrams and code examples. Check it out!
Are you the kind of person who doesn't like taking down the skeletons and spiders until after January? Well, we've got the ADABOX for you. This is electronics at its most spooky! ADABOX 009 is Halloween themed, for all of us who love scares, costumes, and (of course!) candy. OK so we didn't fill this ADABOX with candy corn, but we did curate a collection of inspiring electronics to make you Halloween more electric. You might have so much fun, you'll celebrate it year round!
GBoard is an alternate keyboard for Android Devices that lets you type using Morse code. This has seen use for people with limited mobility, but it can also be useful for practicing your morse code skills. The goal of this project is to build a simple input device for GBoard that doesn't require soldering or elaborate construction techniques. We'll be using a Circuit Playground Express to build this project. We have a few different versions we'll be demonstrating - from the simplest using the two onboard buttons, to using capacitive touch inputs, to connecting up some alligator clips to big-and-easy-to-press arcade buttons.
Circuit Playground Express has the ability to transmit and receive IR signals. You can use CircuitPython to send and receive messages using IR. This guide covers the basics of Circuit Playground Express IR and shows you how to use CircuitPython to communicate between two Circuit Playground Expresses!
Robotics has often been a lot of work. With modern hardware and software, it is now possible to get up and going quickly in a single sit-down, in as little as 15 minutes. Using Adafruit Circuit Playground Express with Crickit, you can actually have a movement + sound project running quickly with a satisfying sense of accomplishment.
You already have Git setup, and you have a GitHub account. You want to contribute to an open source project like CircuitPython, 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, and before you know it, you'll be a pro contributor. Pick a project, find an issue, and let's get started!
Using a Circuit Playground Express with CircuitPython's sound file and accelerometer support, we'll build a multi-voiced percussion instrument and blues chord progression player. Tapping the instrument will play the sound of a variety of selectable percussion instruments or step you through a blues chord progression one beat at a time. The project also includes a hack to connect the Blues Playground to a guitar amplifier for jamming on the big stage!
