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.

In this tutorial, we'll walk you through using the SparkFun Audio Player Breakout in combination with the Qwiic Twist to let you select and play tracks from a microSD card. It's a compact and powerful way to add audio interactivity to your prototype using simple I2C and serial connections.

Learn how to use the DAC of an Arduino to create a simple function generator capable of producing square, sine, and sawtooth waveforms.

Let’s take a look at how to use the analog-to-digital converter (ADC) in an STM32 microcontroller. To make conversions happen more quickly, we can use the direct memory access (DMA) controller to pipe data directly from a peripheral (like the ADC) to memory and vice versa.
