Build a Real-Time Vibration Spectrum Analyser with Arduino Uno & OLED

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

Create an 8‑band vibration frequency spectrum analyser that reads real‑time acceleration data from an ADXL345, runs the ArduinoFFT library to compute frequency magnitudes, and plots them as a dynamic bar graph on a 0.96‑inch OLED. This project is perfect for engineering students exploring signal processing, IoT enthusiasts monitoring machine health, or makers building vibration‑interactive installations.

What You'll Build

By the end of this kit, you’ll have a working spectrum analyser that displays the frequency content of vibrations from motors, bridges, or even footsteps. You’ll see how mechanical motion translates into digital frequency bands, and you can use it to detect imbalance in fans, pumps, or any rotating machinery. The analyser refreshes the spectrum in real time, making it a powerful teaching tool for signal processing and embedded systems.

What You'll Learn

• Interfacing ADXL345 accelerometer with Arduino Uno via I2C, configuring sensitivity and sampling rate
• Implementing real‑time Fast Fourier Transform (FFT) using the ArduinoFFT library on a microcontroller
• Visualizing frequency data on an OLED display by drawing dynamic bar graphs
• Optimizing Arduino code for 100 Hz sampling and real‑time spectrum updates

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is ideal for CBSE Class 11‑12 students exploring physics and computer science integrations, B.Tech ECE/EEE undergraduates building their first embedded system project, or Smart India Hackathon teams working on predictive maintenance and IoT. It’s also well‑suited for ATL Tinkering Labs and university mini‑projects at IITs, NITs, VIT, and BITS Pilani.

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.
