# "LED" is a special designation for Pico's on-board LED.
# Change it to a number (without quote marks) when you want to use a GPIO pin.
# Pin.OUT is how you tell the board that you want to use the pin as an output.

# A while loop setup this way is how to have code do something forever:
while True:
	led.on() # turn the on-board LED on
	sleep(1) # wait here for 1 second
	led.off() # turn the on-board LED off
	sleep(1) # wait here for 1 second
