### Micropython LED Blinky Code

``` python
import esp, esp32, time, os, _thread
from machine import Pin, SoftI2C

# An infinite loop thread to blink LED
def status_led():
    # Blink pattern blink-blink-pause
    while True:
        led.value(1)
        time.sleep_ms(250)
        led.value(0)
        time.sleep_ms(250)
        led.value(1)
        time.sleep_ms(250)
        led.value(0)
        time.sleep_ms(750)
