4×3 12-Button Keypad for Arduino & Microcontrollers

Introduction:
The 4×4 16-button keypad is a membrane switch matrix array designed to interact with microcontrollers like Arduino. It allows for input through buttons arranged in a grid layout, offering a user-friendly interface for various projects such as security systems, home automation, and more.

Details:

• 16 buttons arranged in a 4×4 matrix, perfect for creating a digital interface.
• Compatible with microcontrollers like Arduino, PIC, and AVR.
• Uses a simple connection to control and detect button presses.
• Ideal for projects that require numeric or alphanumeric input.

Highlights:

• High-quality plastic keys.
• Membrane switch matrix array for easy integration with Arduino controllers.
• Space-saving design, perfect for projects where limited space is available.
• Simple and efficient button scanning with minimal wiring.

Features:

• 16 Keys: A grid of 16 buttons, arranged in a 4×4 layout, for easy data entry.
• Matrix Switch: Uses a matrix array for detecting key presses, which minimizes the number of input pins needed on the controller.
• Easy Integration: Directly compatible with Arduino and other microcontrollers such as PIC and AVR, making it ideal for DIY projects.
• Durable Construction: Built with high-quality plastic keys that withstand frequent usage.
• Compact Design: Compact footprint to fit easily into tight spaces.

How to Use:

1. Wiring: Connect the rows and columns of the keypad to the microcontroller’s input/output pins.
2. Library: Use a keypad library (such as the Keypad library in Arduino IDE) for easy coding.
3. Key Press Detection: The library helps detect key presses by scanning the matrix and identifying the row and column of the pressed key.
4. Programming: Write simple code to handle keypresses for various applications like numeric entry, menu navigation, etc.
