16 Key Membrane Switch Keypad 4x4 Keypad for Arduino

Features: 1.The Keypad library allows to read a matrix type keypad. 4 4 numeric keypads are most widely used in numerous mini project which requires the user or the operator to give command to the system or to feed in some data.2. Bear in mind that you don't need the outer two pins on the left and right for wiring. It's the inner 8 pins that matter.3.If you solder on a header, we highly recommend laying down some flux on the pads first, inserting the header pins, then soldering4. The standard Keypad library for Arduino works out of the box with this particular device.Description :Keyboard for the pin interface.4X4 design, 10 numeric keys, 4 English keys,2 function keys. There is a switch connecting each row and column. So the combinations of rows and columns makes up the 16 inputs.Circuit board is PCB double-panel Package includes : 1 x Membrane Matrix Keypad
