16 Key 4 x 4 Membrane Switch Keypad 4x4 4*4 Matrix Array Matrix Smart Car keyboard for arduino Diy Kit
Product description:
This 16-button keypad provides a useful human interface component for microcontroller projects.
Convenient adhesive backing provides a simple way to mount the keypad in a variety of applications.
It's made of a thin, flexible membrane material with an adhesive backing so you can attach it to nearly anything.
The keys are connected into a matrix, so you only need 8 microcontroller pins (4-columns and 4-rows)
to scan through the pad. Check the tutorials tab for links to an Arduino library and example code.
