Note You can easily copy and paste code from the online version of this Guide. Use caution with the
PDF version, as it may not maintain essential indentations.
import machine
from machine import Pin
led = Pin("D4", Pin.OUT, value=0)
# One might expect 0 to mean OFF and 1 to mean ON, and this is normally the case.
# But the LED we are turning on and off is setup as what is# known as "active
low".
# This means setting the pin to 0 allows current to flow through the LED and then
through the pin, to ground.
3. To turn it off, type the following and press Enter:
led.value(1)
You have successfully controlled an LED on the board using basic I/O!
