#Import Pin class from machine library to configure GPIO Pins.
from machine import Pin
#Import utime library to implement delay
import utime
#create an object of Pin class and set GPIO Parameters (GPIO Pin, Direction).
led_gpio16 = Pin(16, Pin.OUT)
#Create an infinite loop. This is similar to while(1) in C.
while True:
    #Set value to 1 to turn ON LED.
    led_gpio16.value(1)
    #sleep_ms function provides delay in milliseconds.
    utime.sleep_ms(100)
    #Set value to 0 to turn OFF LED.
    led_gpio16.value(0)
    #Provide another 100ms delay to see the LED Blinking.
    utime.sleep_ms(100)
