Gravity: Digital RED LED Light Module

The Gravity: Digital RED LED Light Module is an easy-to-use digital visual indicator designed for beginners, students, and makers working with Arduino. It integrates directly with IO and sensor expansion shields to deliver straightforward status lighting for electronics and robotics projects.

Expansion shield integration

This module is designed for seamless connection to standard IO and sensor expansion shields. Its plug-and-play layout allows Arduino starters to add clear visual feedback without complicated breadboard wiring.

Active-low circuit protection

The module is wired to turn the LED on when the signal pin receives a logic low signal. This default active-low setup prevents the LED from drawing excessive current and damaging microcontroller I/O pins.

Configurable trigger logic

If your application requires active-high triggering, the cable wiring can be customised. Switching the green signal wire with the black ground wire, and moving the red voltage wire to the original signal position, enables logic high operation.

Standard digital pinout

The module features a three-pin digital interface consisting of a control terminal, power supply, and ground. This standard layout ensures simple wiring and reliable operation with digital microcontroller ports.

Supplied connection accessories

Each pack includes one digital red LED light module and one compatible 3-pin digital sensor cable (SKU: FIT0011) for quick setup.
