2. Configurazione e connessione
This section details the steps required to correctly connect the Big Key Module Button to your development board.
2.1 Descrizione del pinout
Each button module features a 3-pin interface. Understanding these pins is crucial for proper connection.
- VCC: Power supply input (3.5V to 5V DC).
- TERRA: Collegamento a terra.
- FUORI: Digital output pin.

2.2 Fasi di connessione
- Collegare il VCC pin of the button module to the 3.3V or 5V power supply output of your development board (e.g., Arduino, Raspberry Pi).
- Collegare il Terra pin of the button module to the Ground (GND) pin of your development board.
- Collegare il FUORI pin of the button module to a digital input pin on your development board.
- Ensure all connections are secure and correctly aligned to prevent damage to the module or development board.

3. Istruzioni per l'uso
The Big Key Module Button operates as a simple digital input device.
- When the button is premuto, IL FUORI pin will output a High Digital Level (typically 3.3V or 5V, depending on VCC).
- When the button is rilasciato, IL FUORI pin will output a Low Digital Level (typically 0V).
You can read the state of the button using the digital read function on your microcontroller. For example, in Arduino, you would use digitalRead(pinNumber) to get the current state.
4. Manutenzione
To ensure the longevity and reliable operation of your Big Key Module Buttons, follow these maintenance guidelines:
- Pulizia: Keep the modules free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using liquids or abrasive materials.
- Magazzinaggio: Store the modules in a dry, cool environment, away from direct sunlight and extreme temperatures.
- Gestione: Handle the modules by their PCB edges to avoid touching the electronic components or bending the pins.
5. Risoluzione Dei Problemi
If you encounter issues with your Big Key Module Button, refer to the following troubleshooting tips:
- Nessun output/Output errato:
- Verify that VCC and GND connections are correct and secure.
- Garantire l'alimentazione voltage rientra nell'intervallo specificato (3.5 V - 5 V).
- Check the connection of the OUT pin to your microcontroller's digital input.
- Test with a different digital input pin on your microcontroller.
- Inspect the module for any visible damage or bent pins.
- Il pulsante non risponde:
- Ensure the button is fully pressed and released.
- Check for any physical obstructions preventing the button from moving freely.
