Ultrasonic Levitation Audio Driver Variant 18 Kit with Arduino Mega
Build a Sound-Modulated Ultrasonic Levitator with Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This isn’t a simple sensor circuit — you’ll assemble a 16-element ultrasonic phased array driven by an Arduino Mega that levitates polystyrene beads at standing wave nodes behind the transducers. Feed in an audio signal and the levitation field dances: beads rise, fall, and shift in response to music or voice. It’s a pure intersection of acoustics, embedded control, and signal conditioning that feels like science fiction on your workbench.
What You'll Build
You’ll solder and wire a bi-directional driver stage with L298N modules to power sixteen 40kHz transducers in a tightly spaced grid. The Arduino Mega generates precisely timed square-wave bursts, creating an interference pattern that traps tiny foam beads mid-air. Inject any audio source via a line-level input, and the firmware translates amplitude and frequency into real-time phase adjustments — your levitated particles become a tangible waveform display.
What You'll Learn
- Phased array beamforming principles using multiple ultrasonic transducers
- High-current switching with L298N H-bridges and diode protection networks
- Real-time audio sampling and FFT-based modulation on Arduino Mega
- Soldering and debugging a dense, custom PCB prototype layout

Who This Kit Is For
B.Tech ECE and applied physics students from IITs, NITs, VIT, or BITS tackling final-year projects on acoustics will find a ready-to-scale experimental platform. It’s also built for Smart India Hackathon teams needing a hardware demo that merges signal processing with physical interactivity. CBSE Class 12 students who have moved beyond Arduino basics and want a university-level challenge will appreciate the deep dive into phased arrays and audio DSP.
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?
Scan the QR code in the box to launch the AI companion, which knows every wiring detail and common pitfalls for this levitator. You can also send a photo of your board to our WhatsApp support and get a reply within hours.
Does the kit include an audio input interface?
The Arduino Mega handles line-level audio directly via its analog pins — you’ll wire a 3.5mm jack (not supplied) to the ADC input as shown in the schematics. The AI companion provides pin mappings and sample code for proper DC biasing.
Can I levitate objects heavier than polystyrene beads?
The 40kHz array and driver stage are tuned for very light particles under 2mm diameter. Heavier objects require higher voltage transducers and a far more complex driver; this kit intentionally focuses on the audio modulation challenge rather than raw lifting force.
Is this kit suitable for a group hackathon build?
Yes, the 8–10 hour build time is realistic for a team of two or three with solid soldering experience. The clear partition of transducer soldering, driver wiring, and Arduino coding lets you parallelize the work efficiently.
