Ever dreamed of playing an instrument without ever touching it?

It sounds like sci-fi, but it’s actually a mix of physics, hardware, and a few lines of Python code. As part of the Girls in Digital Week at the end of March, we are inviting you to dive into the world of creative making and physical computing!

What’s an Ultrasonic Theremin?

A traditional Theremin is an instrument played by moving your hands near antennas. In our workshop, we build a modern version using a Raspberry Pi Pico W and ultrasonic sensors.

Move your hand closer: the pitch goes up.
Pull it away: the pitch drops.
The result? Spooky sci-fi sounds, electronic beats, or experimental melodies—all controlled by your movement in mid-air.

What you will do:

The Making Part: Learn how to wire up HC-SR04 ultrasonic sensors on a breadboard.
The Coding Part: Write a Python script that translates distance measurements into real-time sound.
The Creative Part: Experiment with different frequencies and find your own unique "digital voice."

Who can join?

This workshop is designed for girls and non-binary persons aged 13 to 18. Whether you are a coding pro or have never touched a circuit board in your life — everyone is welcome! We start from scratch and explore together.
