Programming the user LED on the CPU card

Write a function that blinks the LED once with a delay that is passed as a parameter:

def blink_once(delay): 

Test the function with a main program calling is with different delays.

Use the function to implement a program that blinks an SOS: 3 short pulses, followed by 3 long pulses, followed by 3 short pulses, followed by a 2s pause. You may use a 200 ms delay for the short pulses and 700 ms delay for the long ones.

Reading the pushbutton

Write a program that reads the push button state ever 100 ms and prints its state (pressed or released)

Improve the program printing the state only when there was a state change.
