DFROBOT Gravity Digital Blue LED Light Module

The DFROBOT Gravity Digital Blue LED Light Module is a brilliant and beginner-friendly component for Arduino-based electronics projects. Featuring a vibrant, shiny blue LED, this module is specifically designed for easy integration with an Arduino IO/sensor expansion shield, allowing hobbyists and students to quickly add programmable lighting to their creations.

A key design feature is its low-current activation. The LED is wired to illuminate when the signal pin is set to LOW. This intelligent configuration prevents the LED from drawing excessive current from the microcontroller's pins, offering a safer and more reliable connection that protects your valuable Arduino board.

Connection is simple and straightforward thanks to its standardised 3-pin Gravity interface:

• Pin 1: Control Terminal (Signal)
• Pin 2: Power Supply (VCC)
• Pin 3: Ground (GND)

This plug-and-play design eliminates the need for complex wiring or soldering, making it an ideal choice for educational settings, rapid prototyping, and embedded design development. It is perfectly suited for learning the fundamentals of digital output control, IoT (Internet of Things) device indicators, and interactive electronics projects.

Compact and lightweight, the module is built for durability and ease of use within the respected DFROBOT Gravity series ecosystem. Whether you are building a status indicator, a decorative light, or an interactive art piece, this blue LED module provides a reliable and vivid lighting solution.

Key Features:

• Vivid Blue Output: Features a bright, shiny blue LED for clear visual indicators.
• Low-Current Design: Activates on a LOW signal to protect microcontroller pins from overcurrent.
• Gravity Compatible: Uses a standard 3-pin connector for instant plug-and-play with IO expansion shields.
• Beginner Friendly: Perfect for Arduino starters, STEM
