Sealed Membrane 4*4 button pad with sticker



Description

The 4x4 Keypad is a versatile, general-purpose input device featuring 16 buttons arranged in a 4x4 matrix configuration. Designed for convenience, its adhesive backing allows it to be easily affixed to any flat surface. The keypad quickly integrates into your projects; just connect it to your system, and it's ready to use.

One practical application is in security systems. By connecting the keypad to a microcontroller, you can create a passcode entry system for secured door access. Users input a sequence of numbers, and the system checks for a match before triggering actions, such as unlocking a door or turning on an indicator light.

Another functional project involves smart home automation. The keypad can serve as a control interface for managing multiple devices. Assign each button a different function, like turning lights on or off, adjusting thermostat settings, or activating appliances, providing a centralized hub for smarter living.

The keypad is constructed with a resilient sealed membrane, offering durability and longevity even with frequent use. This ensures reliable performance in various environments. Whether you’re building an interactive display or prototyping a digital interface, the 4x4 Keypad is a crucial component that offers both simplicity and functionality.
