This compact illuminated push-button module is designed for interactive electronics and quick prototyping. A transparent cap sits over an internal red LED, giving instant visual feedback when the button is pressed.
The module provides a simple digital output for microcontroller input detection: when pressed, it outputs High and the internal LED lights up; when released, it outputs Low and the LED turns off. The Gravity PH2.0 connector makes wiring straightforward with compatible Gravity boards, Arduino projects, micro:bit controllers and other suitable development platforms.
It is well suited to classroom experiments, DIY control panels, game inputs, robotics interfaces and human-machine interface prototypes. The pack includes one Gravity: LED Button - Red and one Digital Sensor Connector.
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
Specifications:
- Operating Voltage: +3.3-5V (3.3V is recommended)
- Output: digital
- Connector: PH2.0-3P
- Dimension: 27×26.5mm/1.06×1.04”
- Colors Available: red, yellow, green, blue, white
Jargon buster
Plain-language definitions for the technical terms used above.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
