Keypad Example

This is an example code that demonstrates the usage of a keypad with an Arduino board. The code allows you to read key presses from a 4x4 keypad and control LEDs based on the pressed keys.

Circuit Diagram

Prerequisites

• Arduino board
• Keypad library

Installation

1. Connect the keypad to your Arduino board based on the provided pin connections in the code.
2. Install the Keypad library if you haven't already.
3. Upload the code to your Arduino board.

Usage

1. Open the Serial Monitor in the Arduino IDE.
2. Press keys on the keypad.
3. The pressed key will be displayed in the Serial Monitor.
4. LEDs will be controlled based on the pressed keys.

Customization

• Modify the keypadLayout array to change the key mappings on the keypad.
• Adjust the pin connections in the rowPins and colPins arrays according to your circuit setup.
• Customize the LED pin (ledPin) to match your circuit configuration.
