class gpiozero.LED(pin*active_high=Trueinitial_value=Falsepin_factory=None) is a while loop to blink the LED every one second.

Five methods of blinking an LED.  I placed a Red LED on GPIO 24 and Blue LED on GPIO 18.   I could have done the same connection through the single supply logic level converter.   It could have been 5V for the LED instead of 3.3V.
