Add Bluetooth Low Energy (BLE) connectivity to your RP2040 by adding an Adafruit AirLift ESP32 processor. This guide covers upgrading the BLE firmware on an AirLift module, examples for using the RP2040 as a Bluetooth peripheral with CircuitPython, and instructions to adapt existing CircuitPython BLE code for use with the AirLift.

Connect your Raspberry Pi RP2040 CircuitPython project to the internet by adding an Adafruit AirLift breakout board. In this guide, you'll wire up a Raspberry Pi Pico RP2040 with an AirLift breakout board. You'll connect your Raspberry Pi Pico to the internet and parse raw text and JSON data. Finally, you'll connect to Adafruit IO to send and receive data from your Pico.

Never miss a meeting again with this Google Calendar Event Display. This project uses a MagTag to fetch and display upcoming events from your Google Calendar. This CircuitPython project uses the Google Calendar API to retrieve a list of the latest events from your Google Calendar and displays them on the MagTag's crisp e-Ink screen. Between fetching new events on your schedule, the MagTag goes into a deep sleep mode to conserve battery life. 

Never miss a meeting again with this Google Calendar Event Display. This project uses an Adafruit PyPortal to fetch and display upcoming events from your Google Calendar. This CircuitPython project uses the Google Calendar API to retrieve a list of the latest events from your Google Calendar and displays them on the PyPortal's LCD screen.

Stay up to date with this MagTag Twitter display. This guide shows how to use an Adafruit MagTag, CircuitPython and the Twitter API to display the latest tweets from a Twitter account.

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.
