Description: 1. Design and Construction: The 4x4 Membrane Keypad is a flat, compact input device with a membrane design that includes a rubber keypad layer sandwiched between two circuit layers. It consists of 16 individually labeled keys arranged in a 4x4 matrix. 2. Functionality: This keypad functions as a standard input interface for various IoT projects and applications. Each key press sends a specific digital signal to the microcontroller or processor, allowing for easy programming and control. 3. Durability: Membrane keypads offer increased durability compared to traditional mechanical keypads. Their rubber keys are less prone to breaking and can withstand more environmental conditions, making them suitable for outdoor IoT projects. 4. Customizable Layout: The 4x4 Membrane Keypad is often customizable, allowing users to assign specific functions or codes to each key. This feature is essential in automation and control systems where quick and precise input is required. 5. Waterproof: Many
