Kimat One Wire Keypad module


SKU: LC-015 Category:


The Kimat One Wire Keypad module instantly simplifies
the implementation of a 4×4 or 3×4 keypad matrix. It
uses just one analog pin as opposed to 7 or 8 pins
without this module. It utilizes an array or resistors
carefully chosen to allow unique voltage output for
each keypress. It is then read by the
microcontroller/Arduino ADC (analog) pins for

Usage is very simple:
