Ultrasonic Levitation Audio Driver Kit with Arduino Mega
Make Sound Visible: Arduino Mega Ultrasonic Levitation Audio Driver Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Construct a 16‑transducer ultrasonic array that levitates polystyrene beads in mid‑air and lets you control their position with an audio source. Connect a music player and watch the beads dance to the rhythm, transforming invisible sound into a dynamic physical display. This is a complete hardware‑software system built around Arduino Mega, with every component selected for 40kHz phased‑array operation.
What You'll Build
You will assemble a working acoustic levitation platform that uses a phased array of 40kHz transducers, driven by two L298N driver boards. The Arduino Mega generates precise PWM signals to create standing‑wave nodes, trapping polystyrene beads. With the audio modulation circuit, the levitation pattern shifts in real time — bass drops and frequency changes become visible motion. The final project is a striking demonstration for engineering showcases, hackathon exhibits, or interactive art installations.
What You'll Learn
- Calibrate a 40kHz ultrasonic phased array to form stable levitation nodes using Arduino Mega timers
- Program multi‑channel PWM with phase offsets to steer the acoustic field
- Sample an audio input and map amplitude to transducer drive strength for real‑time modulation
- Assemble high‑current driver circuits with L298N bridges, 1N4007 flyback diodes, and decoupling capacitors on prototype boards

Who This Kit Is For
This advanced kit is intended for B.Tech ECE/EEE final‑year students looking for a hardware‑heavy capstone project on phased arrays or acoustic levitation. It also suits M.Tech researchers and faculty at IITs, NITs, VIT, BITS and other engineering institutions who need a ready‑to‑build demonstration. Makers with prior soldering experience will appreciate the challenge, especially when preparing for Smart India Hackathon or technical festivals.
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?
Our AI companion provides step‑by‑step visuals and code walk‑throughs trained on this kit. You can also message us on WhatsApp and receive personalised guidance within 12 hours.
How do I interface the audio input to modulate the levitation field?
The kit includes a schematic that feeds a line‑level audio signal into an analog pin of the Arduino Mega. The build companion details the sampling routine and shows how amplitude values adjust PWM duty cycles in real time.
Do I need prior experience with soldering and high‑frequency circuits?
Yes, this is an advanced kit. You should be comfortable soldering 40kHz transducers onto prototype boards and handling 12V driver circuits. The AI companion covers safety notes and joint inspection techniques.
What kind of audio source works best?
Any line‑level source like a smartphone, MP3 player, or function generator works. Bass‑heavy tracks produce dramatic levitation movements, while a pure sine wave at resonant frequency yields the most stable bead suspension.
40kHz ultrasonic transducer array levitates small polystyrene beads. Audio input modulates levitation field.
