Electronic keypads allow the ability to permit or deny the use of the entrance via a code which can be entered by using a numeric code, or PIN. They come in a wide variety of designs and can be used with computers as part of a system, or standalone to grant access to one door with the minimum of set up time.
This electronic switch and Keypad which includes 4×1, 2×2, 3×4, 4×4, 4×5, 7×7 matrix Keypad, Seeedstudio grove. If certain applications are developed of processors with few pins then that system cannot afford to provide more pins to Iinput device. At that time using the keypad module is ideal, as it can give 16 key inputs for using 8 terminals.
