Add animated hearts of colour to costumes, props and wearable projects without trying to sharply bend a flexible LED strip. This strand uses individual heart-shaped NeoPixel pixels connected by cable, making it easier to position each light where you need it.
Each of the 20 hearts contains a single RGB NeoPixel. The pixels are individually addressable, with 8 bits per RGB channel, so each heart can be set to any of 16-million colours.
NeoPixels are 5050-sized LEDs with an embedded microcontroller inside the LED. Each LED acts like a shift register, reading incoming data on the input pins and shifting the previous data out on the output pin, while the PWM is handled inside each LED chip after brightness is set.
The strand has JST 3-pin SM connectors on both ends so multiple strands can be chained together. The red wire is +5V, the middle wire is data, and the black wire is ground; the connector with pins is the input and the connector with holes is the output. Adafruit provides a NeoPixel tutorial covering wiring, power usage calculations and example code.

- Revision History: As of November 5, 2024 - this strand has different 'internal' color ordering. It's now BRG not RGB, so you'll need to change your firmware or configuration to account for the pixel configuration.
A fun choice for wearable electronics, cosplay, festive decorations and animated light-up gifts. Remember to configure your code for the BRG internal colour ordering on current strands.
Jargon buster
Plain-language definitions for the technical terms used above.
- Colour depth
- Colour depth describes how many different colours a display can show. A 65K-colour display can show about 65,000 colours, which is useful for icons, graphs, and simple full-colour interfaces but is less detailed than modern phone or computer screens.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
