Pixel Heart Animation Kit with Arduino Uno
Create a Mesmerizing Beating Heart Animation with Arduino and MAX7219 LED Matrix Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform a simple 8x8 grid of red LEDs into a lifelike beating heart that pulses endlessly. Designed as a first introduction to animated displays, this kit turns abstract code into a tangible, moving pattern kids can show off, tweak, and gift. Perfect for a bedroom decoration, a Valentine’s Day surprise made by hand, or a school science exhibit that demonstrates the magic of pixels.
What You'll Build
A portable animated heart display on an 8x8 MAX7219 LED matrix, controlled by an Arduino Uno. The included code creates a smooth heartbeat animation that loops continuously. You’ll have a working, battery-powered device you can frame or mount—and because the pattern is built from a bitmap, you can customize the heart shape, add a flicker, or swap in entirely new designs.
What You'll Learn
- Connecting an LED matrix using only five wires and understanding SPI communication basics
- Uploading code to Arduino Uno and installing the MD_MAX72XX library
- How pixel arrays create smooth animations by updating rows at high speed
- Modifying brightness, speed, and heart shape to express your own creative ideas

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify every part | Pre-tested as a system |
| Build support | Forums and scattered tutorials | AI companion trained on this exact project |
| Time to first working build | Days of debugging | Hours, with step-by-step guidance |
| Shipping coordination | Multiple sellers, multiple delays | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
Young tinkerers as young as 5 with adult help, CBSE Class 5–10 science and computer students tackling first hardware projects, ATL Tinkering Lab members needing a quick display module, and parents who want to introduce coding through a concrete, visual reward. It’s also ideal for Smart India Hackathon junior tracks, hobby clubs, and DIY gift-makers.
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.
What if I get stuck during the build?
Scan the box QR code to start a chat with the AI companion, which knows every step for this kit. If you need a human, our WhatsApp support responds within hours.
Can I change the heart to another animation?
Absolutely. The code uses a simple bitmap array; you can edit it to draw a smiley, letter, or any 8x8 pattern. The AI companion can guide you through creating your first custom animation.
Does this kit require soldering?
No soldering at all. Everything connects with the included jumper wires on a breadboard (not included but any standard 830-point board works). The circuit is safe and reusable.
Is this kit safe for a 5-year-old?
The 9V battery makes it low-voltage and safe, but adult supervision is recommended for handling tiny components and the battery snap. The build process is a great parent-child activity.
MAX7219 8x8 matrix displays animated beating heart pattern on loop. First LED matrix animation.
