WS2812B 8x8 Matrix Visualiser Kit with Arduino Uno — Build a Live Sensor Heatmap with Custom Colour Gradients

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

Imagine an 8×8 grid of NeoPixels that glows blue for cool temperatures, shifts to green for comfortable humidity, pulses orange when atmospheric pressure drops, and brightens as ambient light increases. This kit equips you to build exactly that — a real-time environmental heatmap that reads three sensors and maps their values to a custom colour gradient you define in code.

What You'll Build

A 64-pixel LED display that reads temperature and humidity from the DHT22, atmospheric pressure from the BMP280, and ambient light from the BH1750. You wire the sensors, load the Arduino sketch, and instantly see your room’s climate painted in colour. Customise the gradient to map low-to-high readings across any colour range you like, turning raw numbers into an intuitive visual dashboard you can mount on a wall, carry to a science fair, or integrate into an IoT prototype.

What You'll Learn

• Interface I²C and one-wire sensors on a single Arduino bus
• Calibrate and map sensor readings to a 0–255 colour scale for NeoPixels
• Design custom colour gradients using RGB colour theory
• Debug real-time serial output and validate sensor data integrity

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for CBSE Class 11–12 students building a computer science or physics investigatory project, B.Tech ECE/EEE undergraduates prototyping for lab submissions, and ATL Tinkering Lab facilitators running sensor-and-display workshops. Teams preparing for the Smart India Hackathon will find this a fast-track environmental monitoring display; IIT, NIT, VIT, and BITS Pilani student clubs can use it for data visualisation demos and beginner IoT training.

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.
