Micropython button debouncer

Micropython implementation of a debounced button. Tested to work well with the Raspberry Pi Pico.

How to use:

1. Connect a button to ground and any pin of the microcontroller
2. Upload button.py to the microcontroller
3. Use according to the below example script

Features:

• Simple and easy to use
• Interrupt/Callback based -> no polling
• Supports short and long presses
• Software debounce -> no additional hardware required

Example code:

from button import Button

button_pin = 18

def click():
    print("Short click")
    
def long():
    print("Long press")

b = Button(button_pin, click, long)

Debouce time and long-press duration can be modified using:

b = Button(pin_number, callback, long_press_callback=None, debounce_time_ms=50, long_press_duration_ms=2000)
