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 (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
