Description

The Gravity LED Button is a compact, illuminated push-button module for interactive electronics, prototyping and classroom projects. A transparent cap shows a red indicator LED that lights while the button is pressed, giving instant visual feedback. It connects with a PH2.0 Gravity connector and works with Arduino and micro:bit.

When pressed down, the module outputs HIGH and the LED lights up. When released, the output goes LOW and the LED turns off.

Features

Integrated LED lights up automatically when the button is pressed
Digital signal output for simple microcontroller input detection
Transparent button cap for clear visual indication
Gravity PH2.0 connector for quick plug-and-play wiring
Multiple LED colour options: red, yellow, green, blue, white

Applications

Interactive electronics projects
STEM education experiments
Robotics control interfaces
DIY control panels
Game input buttons
Human–machine interface prototypes

Connection diagram

Getting started (Arduino)

Connect D to digital pin 2, + to 3.3 V (or 5 V) and - to GND using the included cable
In setup(), use pinMode(2, INPUT); in loop(), digitalRead(2) returns HIGH while the button is pressed
Open the Serial Monitor and press the button - the reading changes and the cap lights up

On micro:bit, use the MakeCode "digital read pin" block or DFRobot’s Mind+ software.
