MicroPython library for interfacing with a keypad matrix

![](https://github.com/PerfecXX/MicroPython-SimpleKeypad/blob/main/doc/4x4keypad.png)

## Feature 

- Supports any keypad matrix configuration.

- Easily customizable for different keypad layouts.

- Provides exception handling for error management.

## Example Usage 

Example for 4x4 keypad metrix on MicroPython esp32. 

```python

from machine import Pin

from keypad import Keypad

from time import sleep

# Define GPIO pins for rows

row_pins = [Pin(25),Pin(26),Pin(27),Pin(14)]

# Define GPIO pins for columns

column_pins = [Pin(23),Pin(22),Pin(19),Pin(18)]

# Define keypad layout

keys = [

    ['1', '2', '3', 'A'],

    ['4', '5', '6', 'B'],

    ['7', '8', '9', 'C'],

    ['*', '0', '#', 'D']]

keypad = Keypad(row_pins, column_pins, keys)

while True:

    key_pressed = keypad.read_keypad()

    if key_pressed:

        print("Key pressed:", key_pressed)

    sleep(0.1)  # debounce and delay

```
