Glossy Polyseter Solid Printing Arduino Membrane Keypad For Ventilation Fan Control

Components Needed

1. Arduino Board: Any model (e.g., Arduino Uno, Nano).
2. Membrane Keypad: Typically 4x4 or 4x3 configurations.
3. Connecting Wires: For connecting the keypad to the Arduino.
4. Breadboard (optional): For easier connections.

Wiring the Keypad

1. Identify the Pins: A standard 4x4 keypad has 8 pins.
2. Connections: Connect the keypad pins to the Arduino. For a 4x4 keypad:
   • Row pins (usually 1-4) to any digital pins (e.g., 2-5).
   • Column pins (usually 5-8) to other digital pins (e.g., 6-9).

Explanation of the Code

• Library Inclusion: The Keypad library simplifies the reading of keys.
• Keypad Definition: Define the layout and pins used.
• Setup: Initializes serial communication for debugging.
• Loop: Continuously checks for key presses and prints the pressed key.

Additional Tips

• Debouncing: The library handles key debouncing, but if you notice issues, consider adding a debounce delay.
• Customization: You can change the key layout and the number of rows/columns based on your keypad.
• Libraries: Make sure to install the Keypad library via the Arduino Library Manager.
