A Modular Interactive Sequencer for kids
Overview
Wave is a modular, interactive sequencer designed for physical engagement and flexible arrangement. Using hexagonal modules connected via joints, users can build and reshape the instrument in a variety of layouts.
Each module responds to weight through a load cell, allowing the pitch to change based on the object placed on it. This tactile interface enables intuitive sound control, offering a unique experience compared to traditional sequencers.
How It Works
-
Modular Design
Hexagonal modules connect via joints, forming custom configurations. -
Weight-Based Pitch Control
Each module uses a load cell to detect weight, which determines the pitch of the step. -
I2C Communication
Each module contains a Slave Arduino that sends data to the Master Arduino over I2C. -
Signal Output
The master processes the input and generates Gate and CV Out signals to control external analog or modular synths. -
Planned Features
- Tempo control
- Expanded CV/Gate behavior
- Custom sequencing logic

Applications
Wave is ideal for experimental music setups, sound installations, or educational environments where interaction, modularity, and sound design meet.
Status
🚧 Wave is currently under development. More updates and documentation will be available soon.
Questions
How big is the Wave PCB?
It measures 30.5 × 73.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wave use?
5 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Wave KiCad files?
From the Yellow-Moonlight/Wave repository on GitHub, at the commit this page was made from: the board is circuit/Wave.kicad_pcb and its schematic circuit/Wave.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wave design in my own project?
Its repository states no licence, so its author keeps all rights: ask Yellow-Moonlight before reusing the design.
