This repository contains the code used in these in Towards Data Science articles:

• Nine Pico PIO Wats with MicroPython, Part 1 & Part 2

• Nine Pico PIO Wats with Rust, Part 1 & Part 2 (forthcoming)

It uses the PIO features of the Raspberry Pi Pico to generate sound and handle input from an ultrasonic rangefinder. The examples include a backup beeper, a melody player, and a theremin-like instrument.

To run the various MicroPython examples, edit the main.py. See the article for some details on getting the code onto the Pico.

To run the various Rust examples, use the following commands:

• cargo run --example backup_demo
• cargo run --example sound_demo
• cargo run --example distance_demo
• cargo run --example distance_debug
• cargo run --example theremin
• cargo run --example theremin_no_pio --release

See the article for some details on getting the code onto the Pico.
