About this document

Arduino Keypad Project Code by VicknesTamil is a document available to read on EtoBox.

This document defines code for a 4x4 keypad input device connected to an Arduino. It initializes constants for the number of rows and columns of the keypad. A 2D array defines the symbols on each button. Interrupts are attached to digital pins to increment or decrement a counter when those pins change state. A GetNumber function reads keypad input and converts it to a numeric value, and functions are defined to handle the interrupts and check the counter value.
