ATL Sound and Acoustics Lab Kit — Visualize Sound Waves with Arduino Serial Plotter

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Turn your classroom into a sound lab where you can generate tones, capture real-world sounds, and watch them come alive as waveforms on your computer screen. This kit turns an Arduino Nano into an oscilloscope, teaching the physics of sound through hands-on experimentation. Perfect for ATL labs and CBSE science practicals, students learn frequency, amplitude, and waveform comparison by building their own measurement system.

What You'll Build

A sound analyzer that uses a buzzer to produce controlled tones, a microphone to capture external sounds, and the Arduino Serial Plotter to display real-time waveforms. By pressing buttons, you can change the buzzer's frequency and observe the resulting sine wave. Then you can measure the environment's sounds—claps, tuning forks, musical instruments—and compare their frequencies and shapes. You'll finish with a working digital oscilloscope that makes invisible sound waves visible.

What You'll Learn

• Generate variable-frequency tones using a piezo buzzer and Arduino
• Capture analog audio signals with a condenser microphone module
• Display real-time waveforms on the Arduino Serial Plotter as a basic oscilloscope
• Compare frequency and amplitude between generated and ambient sounds

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for ATL Tinkering Labs, CBSE Class 9–12 physics practicals on sound, and early engineering undergrads (B.Tech ECE/EEE) at institutes like NITs, VIT, or state universities. Ideal for Smart India Hackathon junior tracks, school science exhibitions, and anyone who wants to replace a costly lab oscilloscope with an Arduino-based alternative for waveform visualization.

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.
