It's a 4×4 Matrix 16 Keyboard Keypad Electronic. A 4x4 matrix keypad‚ also known as a 16-key keypad‚ is an electronic input device commonly used for entering numeric or alphanumeric data. It consists of a grid of 16 keys arranged in a 4x4 matrix format. The matrix keypad is connected to a microcontroller or another electronic device using a matrix wiring arrangement. This allows for efficient scanning of the keypad to determine which key is being pressed. The rows and columns of the matrix are connected to the input/output pins of the microcontroller‚ and by selectively activating the rows and monitoring the columns‚ the microcontroller can detect key presses. The 4x4 matrix keypad is commonly used in various applications‚ such as security systems‚ access control panels‚ electronic locks‚ calculators‚ and other devices where user input is required. It provides a compact and efficient way to input data‚ and its versatility allows for customization based on specific application requirements
