32 LED Heart-Shaped SMD DIY Electronic Kit – Microcontroller Flashing Light

Build your own dazzling heart-shaped LED light display with this fun and educational DIY electronics kit! Featuring 32 SMD LEDs controlled by a microcontroller, this kit cycles through multiple stunning light patterns — making it perfect for electronics hobbyists, students, and makers who love hands-on soldering projects.

⚠️ Please Note: This kit is designed for buyers who have prior experience with circuit assembly and soldering. All components are verified to be in good condition before shipping; however, successful assembly depends on the buyer's skill level. Please read all instructions carefully before beginning.

Key Features

32 SMD LEDs arranged in a heart-shaped pattern for a striking visual display
Microcontroller-driven — uses an 8/10-pin microcontroller to coordinate all 32 LEDs via programmed sequences
Multiple light modes: full on/off flashing, flowing water effect, stack flash, contracting flash from both sides, rotating flash, and more
Standby breathing mode: press the S1 switch to enter standby — the "heart tip" LED pulses in a soft breathing pattern
Easy toggle: press S1 again to return to full working mode
Wide power range: operates on 3–5V DC; higher voltage produces brighter LEDs
Great for learning circuit assembly, soldering practice, and understanding microcontroller basics

Circuit Details

The heart-shaped PCB is home to 32 SMD LEDs wired to a compact microcontroller. Upon powering on, the circuit defaults to active display mode and cycles through a rich variety of flashing patterns. S1 acts as the start/stop switch — one press enters breathing standby mode (only the "heart tip" LED flashes gently), and another press resumes the full animation sequence.

Installation Notes

Mount all components flush against the PCB surface for best results
Pay careful attention to the polarity of each LED and the orientation of the integrated circuit (IC)
Power supply: 3–5V DC (batteries or regulated DC adapter)
Suitable for builders with basic to intermediate soldering experience

Made in Mainland China.

Frequently Asked Questions

Q: Do I need prior electronics experience to assemble this 32 LED heart-shaped DIY kit?

A: Yes — this DIY electronic kit is designed for buyers who already have basic to intermediate experience with circuit assembly and soldering. While the kit is straightforward for those familiar with SMD components and PCB work, beginners may find it challenging. Please review all documentation before starting your build.

Q: What power supply does the 32 LED heart-shaped SMD kit require?

A: The kit operates on a 3–5V DC power supply. You can use standard AA/AAA batteries or a regulated DC adapter. Keep in mind that a higher voltage within this range will produce brighter LED output. Do not exceed 5V to avoid damaging the microcontroller or LEDs.

Q: How many light modes does this microcontroller LED kit support?

A: The kit supports multiple animation modes, including full on/off flashing, flowing water effect, stack flashing, contracting flash from both sides, and rotating flash. In standby mode (activated by pressing the S1 switch), the "heart tip" LED pulses in a calming breathing pattern until S1 is pressed again to resume full mode.
