This tutorial covers how to get CO2 and other environmental readings from the STC31 using both Arduino and MicroPython when connecting the CO2 Sensor Breakout to a compatible development board over Qwiic.

For social distant trick or treating, we thought we’d make a BLE controlled servo claw using the Circuit Playground Bluefruit.

This guide will help with everything you need to get started with the Breadboard Power Supply.

This project provides the current date and time using GPS satellites. Depending on your display, you can draw the time as a digital or analog clock. Or even configure the clock to read military time, adjust the clock for your time zone, or automatically adjust the time for daylight savings time!

This tutorial will focus on setting up your own fixed antenna on your roof or other fixed structure and configuring a minicomputer to serve that data over the internet where it can be accessed by WiFi or more commonly, from a cellular phone or modem.
