Gravity: Digital Blue LED Light Module

The Gravity: Digital Blue LED Light Module is a simple visual indicator designed for Arduino beginners, students, and hobbyists. It connects directly to IO and sensor expansion shields, allowing users to add clear visual feedback to projects with minimal setup.

Beginner-friendly expansion shield connection

This module is designed for Arduino starters and plugs directly into standard IO and sensor expansion shields. It features a blue LED element that provides clear visual signalling for electronics projects.

Active-low logic protection

The module is wired to turn on when the signal pin is pulled low. This active-low setup prevents the LED from drawing too much current directly from the microcontroller, protecting sensitive I/O pins.

Flexible active-high wiring option

To configure the LED to trigger on a logic-high signal, the wiring can be adjusted. Swap the green signal wire with the black ground wire, and move the red voltage wire to the original signal pin position.

Digital interface and pinout

This digital light module features a standard three-pin layout consisting of a control terminal, power supply, and ground connection.

Included package contents

Each pack includes one digital blue LED module and one digital sensor cable (SKU: FIT0011) to facilitate quick hook-up to your system.
