DFRobot Gravity Digital Push Button Green - 3.3V/5V Digital Interface

The DFRobot Gravity Digital Push Button is designed to operate across a wide voltage range of 3.3V to 5V DC. This makes it directly compatible with most common microcontroller platforms like 5V Arduino boards and 3.3V systems such as Raspberry Pi GPIO or ESP32 development boards without requiring level shifting.

Connection is simple using the included Gravity 3-pin cable. Connect the cable from the module's 'D' (Digital) port to any digital input pin on your microcontroller. The cable's pins are color-coded or labeled: yellow (signal) to your chosen GPIO, red (VCC) to 3.3V or 5V, and black (GND) to ground. No additional components are required.

This module provides a raw digital signal from the tactile switch. For reliable reading, implement software debouncing in your code. In Arduino IDE, you can read the button's state by using `digitalRead()` on the connected pin. The signal is LOW when the button is pressed and HIGH when released, which is the standard active-low configuration for such input modules.

No, the integrated LED on this module is directly tied to the button's switch circuit. It lights up automatically when the button is pressed and turns off when released. For independent control of an LED, you would need a separate output module or a different button design that separates the switch and indicator circuits.
