5 Key Matrix Keypad

A 5-Key Matrix Keypad is a compact input device commonly used in embedded systems, microcontroller projects, and DIY electronics. It consists of five push buttons arranged in a matrix configuration, reducing the number of required GPIO pins for interfacing. The keypad operates using a row-column scanning technique, making it efficient for applications with limited I/O availability.

Key Features:

• Compact Design: Small footprint, ideal for space-constrained projects.
• Matrix Configuration: Uses a 2×3 or similar matrix layout to minimize wiring complexity.
• Easy Microcontroller Integration: Compatible with Arduino, Raspberry Pi, and other microcontrollers.
• Multiple Applications: Used in menu navigation, security systems, industrial controls, and interactive projects.
• Reliable Performance: Debouncing techniques can be applied for accurate keypress detection.

This keypad is a practical choice for projects requiring a simple yet effective user input method.
