### Examples

#### Raspberry Pi Pico - Micropython

Library: <https://github.com/mcauser/micropython-tm1637>

 ```
from machine import Pin
import utime
import tm1637

# Define pins for TM1637 display module
TM1637_CLK_PIN = 2
TM1637_DIO_PIN = 3

# Initialize TM1637 display object
tm = tm1637.TM1637(clk=Pin(TM1637_CLK_PIN), dio=Pin(TM1637_DIO_PIN))

# Loop to display a count on the TM1637 display
count = 0
while True:
    count_padded = f'{count:04}'  # Add leading zeros to the number
    tm.show(count_padded)  # Update the display with the number
    count += 1
    utime.sleep(1)
