Design images and animations using Microsoft Expressive Pixels and display them on an Adafruit Matrix Portal. This guide covers installing the open-source Expressive Pixels firmware on an Adafruit Matrix Portal, authoring animations and images, saving images to the Matrix Portal, and triggering animations using the Matrix Portal's GPIO pins.

Build a 3D printed enclosure for your IOT Air Quality Sensor.

Build an internet-connected RGB LED ticker to display the latest data on the Adafruit Learning System. Using the Adafruit Matrix Portal and CircuitPython, you'll build a display which can fetch and display the latest guides from the Adafruit Learning System's API. This project can easily be adapted to a REST API of your choice to scroll data of your choice. Some ideas are scrolling negative COVID-19 tests, sports scores, positive news headlines, or stock prices. 

Build an air quality monitor to track and sense the quality of the air around you. This sensor measures PM2.5 dust concentrations, temperature, and humidity. The sensor is programmed using CircuitPython and periodically sends data to Adafruit IO. Measurements are displayed on an Adafruit IO dashboard for real-time and long-term data visualization.

Control your project using Adafruit IO's schedule actions. Build an internet-controlled lamp and connect it to Adafruit IO to schedule turning the lamp on or off during the week. This project may be adapted to control any AC (mains) appliance or device.

Build an open-source version of an internet-controlled outlet using a PyPortal and a power relay. The outlet is programmed with CircuitPython and connected to Adafruit IO so you can control it from anywhere in the world! Go further with this guide by adding a feedback indicator so you read the appliance power status.

Tout ce que vous devez savoir pour coder avec Microsoft MakeCode

MakeCode de Microsoft es un editor de código para la CircuitPlayground de Adafruit. Puedes arrastrar y soltar bloques o escribir JavaScript. MakeCode está basado en web, ¡así que hay que instalar nada para iniciar!

In this guide, you will build a text-able environmental monitor using the Adafruit FONA shield, a Metro M0/M4 development board and a Bosch BME280 precision sensor. Using CircuitPython, you'll program the Feather to send and receive SMS messages using the CircuitPython FONA library and read environmental data from the BME280 sensor with the CircuitPython BME280 library. 

Build projects that can transmit and receive data from just about anywhere using cellular data! Add cellular networking to your CircuitPython projects with the Adafruit CircuitPython FONA library. Our library handles all the complicated modem commands and setup, so you can connect to the internet right away!

This project uses a PyPortal and CircuitPython to determine the current time and day and display an estimate of the current hour. The clock is customizable for adding new backgrounds, fonts, and font colors.

Read monitor and record your (or someone else's) temperature with this wearable temperature sensor. You can monitor temperature for up to 8 hours on a full charge. Your temperature is sent to Adafruit IO for real-time monitoring and visualization. Receive email alerts for predefined temperature limits.

Tired of trying to authenticate your projects with a wireless network? If you need to add plug-and-play networking, nothing beats Ethernet! Simply plug a standard Ethernet cable into an Ethernet FeatherWing or Shield and use the Adafruit CircuitPython Wiznet5k library for networking. Our CircuitPython library handles DHCP and DNS setup, so you can connect to the internet right away!

Monitor a network of sensors via a Bluetooth connection to a Raspberry Pi. You can then send the data to an internet of things (IoT) service like Adafruit IO for visualization.

Tired of reaching for your phone when you need new 2FA tokens? (Or maybe you don't have a phone!) In this guide you will build a simple device generates TOTP's, using CircuitPython. It uses an Adafruit PyPortal which has WiFi, so it can connect to NTP and obtain the current time on startup. It has a built-in touchscreen display so you can tap to display your token.
