Uncover the Full Light Spectrum with an 18-Channel Arduino Analyser Kit (410nm-940nm)

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 any light source into a live bar chart revealing its secret colour fingerprint. The AS7265x sensor splits the spectrum into 18 calibrated bands-from deep violet at 410 nm to the near-infrared edge at 940 nm-while the OLED plots intensity in real time. Whether you are checking LED quality, comparing plant grow lights, or simply curious about the hidden structure of everyday light, this intermediate-level kit puts a pocket spectrometer in your hands after a single afternoon of building.

What You'll Build

A handheld spectral analyser that reads the full visible range plus near-IR. The AS7265x delivers 18 distinct wavelength counts, each representing a narrow slice of light. The 0.96-inch OLED shows a dynamic bar graph-height equals intensity-so you can instantly contrast a tungsten bulb's warm peak with a white LED's sharp blue spike. All components sit securely on the included breadboard, and the clear wiring guide gets you from unboxing to first measurement in about 4 to 5 hours.

What You'll Learn

• How a multi-channel spectral sensor works and how to read its factory-calibrated data via I2C
• Setting up an OLED display and drawing animated bar charts with Arduino code
• Interpreting a spectral power distribution to characterise different light sources-LEDs, incandescent bulbs, sunlight
• Filtering sensor noise and stabilising readings using the supplied capacitors and resistors

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Built for CBSE Class 11-12 students creating investigatory projects on light, B.Tech ECE/EEE undergraduates prototyping mini spectral analysers, and ATL Tinkering Lab mentors introducing spectroscopy. The kit also supports Smart India Hackathon teams working on rapid material inspection or agriculture light-quality assessment, and hobbyists who want a calibrated reference design they can extend.

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.
