Gravity: Digital Colorful Flashing LED Module

The Gravity: Digital Colorful Flashing LED Module is an interactive lighting component featuring an automatic seven-colour cycling effect. It is an ideal visual indicator for students, hobbyists, and educators building beginner-friendly electronics and robotics projects.

Automatic seven-colour rainbow lighting

The module features an integrated LED that cycles automatically through seven rainbow colours once powered. This delivers dynamic multi-colour illumination without requiring complex colour-mixing code.

Flexible supply voltage support

Operating across a 3.3V to 5V power range, this module works seamlessly with both 3.3V and 5V development boards. It integrates easily into standard microcontroller systems without logic level shifters.

Gravity digital interface connector

Equipped with a standard Gravity 3-pin digital port, the board connects directly to compatible expansion shields. This ensures quick, secure wiring for rapid prototyping and classroom experiments.

Simple digital signal operation

The flashing sequence is activated and controlled using a standard digital output pin. Toggling the digital pin high or low lets users turn the module on and off within their code.
