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.

Let’s look at how to connect a simple I2C device to a STM32 Nucleo board to read temperature data using the STM32 HAL API.

Use an Arduino to read temperature, humidity, and pressure data from a BME280 and send it over a simple LoRa connection to a Raspberry Pi server.
