Build a circuit using your Raspberry Pi that causes an LED to blink when a push button is NOT pressed.
However, the LED should stay on continually when the push button IS pressed.
Video should show the LED blinking when the push button is not pressed,
and it should show that the LED is constantly on while the button is pressed.
The code can be tested without Raspberry Pi board by using print statements
