Here's an interesting way to control an Arduino using data-over-sound, demonstrated by Chirp. They show how to use their SDK to send an RGB value to change the colour of a on-board LED.

The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...

The Nano Every is a pin-equivalent substitute, so previous code and wiring will still work. Arduino has also swapped out the Nano's mini-USB connector in favor of micro-USB.
