## Description

A simple red LED module with a Gravity 3-pin digital interface for plug-and-play connection to Arduino and other microcontrollers via a Gravity IO Expansion Shield. Ideal for beginners learning digital output control. Key Features Gravity Interface – 3-pin plug-and-play connection Digital Control – Simple on/off via a single digital pin Active-Low Design – LED lights when the signal pin is set LOW Specifications Type – Digital Colour – Red Pin Definition – (1) Signal, (2) VCC, (3) GND Package Contents 1× Gravity Digital Red LED Module 1× Digital Sensor Cable Note: This LED is wired active-low — it lights up when the signal pin is set to LOW. This prevents the LED from drawing excessive current from the microcontroller I/O pin. To use it with active-high logic, swap the signal wire (green) with the GND wire (black), and connect the VCC wire (red) to the signal pin's original position.

**Product Type:** physical
