Acoustic Resonance Finder Kit with Arduino Uno
Acoustic Resonance Finder Kit with Arduino Uno – Discover Hidden Frequencies in Tubes and Chambers
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Sweep a tone from 100Hz to 5kHz and watch the MAX9814 microphone amplifier detect the exact resonant frequency of any tube or chamber on the 16x2 LCD. Whether you’re verifying the standing wave pattern of a PVC pipe or measuring the Helmholtz resonance of a bottle, this kit transforms abstract physics into a tangible measurement that you can repeat and analyse in minutes.
What You'll Build
A portable frequency analyser that outputs a clean tone sweep through a passive buzzer, captures sound pressure with a high‑gain microphone, and displays real‑time amplitude on an LCD. The device automatically highlights the frequency where resonance makes the system loudest, giving you a reliable number for lab notebooks, science fair exhibits, or engineering mini‑projects.
What You'll Learn
- Generate and control audio frequencies from 100 Hz to 5 kHz using an Arduino Uno
- Interface a MAX9814 electret microphone amplifier to measure sound pressure levels
- Drive a 16x2 character LCD with an I2C backpack to show live frequency and peak amplitude
- Identify and interpret acoustic resonance phenomena in tubes, bottles, and chambers

Who This Kit Is For
CBSE Class 11–12 students exploring sound and wave physics will find this a ready‑made practical for internal assessments. ATL Tinkering Lab mentors can deploy it immediately for an engaging workshop on resonance. First‑year B.Tech students in ECE, EEE, or instrumentation can use it as a reliable base for a mini‑project or a data‑acquisition demonstrator during Smart India Hackathon or inter‑college tech fests.
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.

How accurate is the resonance detection?
The MAX9814 offers automatic gain control with high sensitivity, and the Arduino code uses a peak-hold algorithm. You can expect repeatable results accurate to within ±5 Hz for typical tubes and chambers.
Can I use this kit to test different objects like bottles or pipes?
Absolutely. The open‑air microphone and broad sweep range let you place any hollow object near the buzzer and mic; the system will find its fundamental resonant frequency without any modification.
Do I need to write my own code?
We provide complete, commented Arduino code pre‑loaded on the Uno. You can modify the sweep range and peak detection logic if you wish, but no coding is required to run the default experiment.
Sweeps tone from 100Hz to 5kHz. MAX9814 peaks at resonant frequency of tube or chamber.
