Gravity: LED Button for Arduino / micro:bit (Green)

Gravity LED Button is a compact illuminated push-button module designed for interactive electronics, prototyping, and classroom projects. A transparent cap reveals an integrated indicator LED that lights when the button is pressed, providing immediate visual feedback during operation. This gravity‑series digital input module simplifies human‑machine interaction in embedded systems while maintaining straightforward wiring through a PH2.0 connector. The illuminated switch integrates smoothly with development platforms such as micro:bit, enabling quick creation of responsive interfaces for experiments, interactive displays, robotics controls, and beginner-friendly hardware demonstrations.

Note: When pressed down, the module outputs High, and the LED lights up. When released, the module outputs Low and the LED turns off.

Integrated LED Visual Feedback

An onboard indicator LED illuminates immediately when the push button is pressed, creating a clear visual confirmation of input status. Such real-time feedback simplifies debugging during circuit prototyping and enhances interactive experiences in educational or exhibition projects. The illuminated push-button design helps learners and developers quickly identify active states in control panels, experimental setups, and physical computing interfaces without requiring additional indicator components.

Plug-and-Play Gravity Interface

A standard PH2.0‑3P Gravity connector enables fast integration with compatible expansion boards and controllers. This plug‑and‑play wiring approach minimizes soldering and reduces setup errors, which is particularly useful in STEM learning environments and rapid prototyping workflows. The digital signal output works reliably with common microcontroller platforms, allowing the illuminated switch module to function as a dependable user input element in robotics, interactive installations, and embedded control projects.

Versatile Interactive Control Element

Multiple LED color options—red, yellow, green, blue, and white—allow flexible design for status indication, game interfaces, and multi-button control panels. The compact board size makes the illuminated input device suitable for handheld prototypes, educational kits, and control consoles. Clear mechanical action combined with visual indication makes this interactive control component ideal for experiments that combine tactile input with visible response.

Typical applications include interactive control panels, educational electronics demonstrations, robotics control interfaces, and beginner-friendly hardware experiments. The illuminated digital switch module enables simple human‑input interaction in creative computing activities, maker projects, and STEM Education environments where immediate visual feedback improves understanding of digital input behavior.
