Reactive Generative Music Installation Kit with Arduino Mega + Ultrasonic
Reactive Generative Music Installation Kit — Arduino Mega + Ultrasonic Sensors
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Step into the intersection of physical space and algorithm-driven sound. This kit lets you build a responsive installation where human movement — detected by PIR and ultrasonic sensors — becomes the raw data for a generative music system. Layer samples, sculpt reverb, and shape soundscapes that shift with every passing visitor. Ideal for gallery installations, experimental performance, or immersive environments.
What You'll Build
You'll assemble a complete, self-contained sound installation. Three passive infrared (PIR) sensors map presence across a room while two ultrasonic sensors measure proximity. The Arduino Mega processes these inputs through a custom generative algorithm that selects and layers samples from dual DFPlayer Mini modules. The MCP4725 DAC applies programmable reverb tails, and the PAM8403 amp drives a stereo pair of 3W speakers. The entire system fits inside a provided enclosure and runs on a single 12V supply.
What You'll Learn
- Designing sensor arrays that convert occupancy and distance into musical parameters
- Programming generative algorithms on Arduino Mega to trigger and layer DFPlayer samples
- Using I²C to control the MCP4725 DAC for real-time reverb and signal processing
- Soldering and assembling a multi-board audio system on prototype PCB, ready for permanent installation

Who This Kit Is For
Sound artists and installation designers building reactive environments. B.Tech ECE/EEE students crafting generative audio for final-year projects or Smart India Hackathon submissions. Advanced hobbyists and professionals who want a cohesive platform to explore sensor-to-music mapping without chasing individual parts. If you've soldered before and understand basic Arduino, you're ready for this project.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI build companion, tuned for this kit, offers step-by-step guidance. For trickier moments, WhatsApp support from our Bengaluru team is included.
Can I use my own audio samples on the MicroSD cards?
Yes. The DFPlayer modules read standard WAV/MP3 files. You can replace the included samples with your own sound library to customize the installation.
Is the kit suitable for permanent public installation?
Absolutely. The enclosure and dedicated 12V supply allow continuous operation. Test sensor positions and audio levels before final mounting.
What soldering skill level is required?
You'll solder headers, wires, and passive components onto three prototype boards. Confident through-hole soldering is essential; the build tutorial includes detailed solder guides.
PIR and distance sensors feed generative music algorithm. DFPlayer layers samples with reverb tail from MCP4725.
