CircuitPython Digital In & Out

The first part of interfacing with hardware is being able to manage digital inputs and outputs. With Circuitpython it's

super easy!

This quick-start example shows how you can use one of the Circuit Playground Express buttons as an

input

to control

another digital

output

- the built in LED

Copy and paste the code block into code.py using your favorite text editor, and save the file, to run the demo

# CircuitPlaygroundExpress_DigitalIO

import time

import board

from digitalio import DigitalInOut, Direction, Pull

led = DigitalInOut(board.D13)

led.direction = Direction.OUTPUT

button = DigitalInOut(board.BUTTON_A)

button.direction = Direction.INPUT

button.pull = Pull.DOWN

while True:

if button.value: # button is pushed

led.value = True

else:

led.value = False

time.sleep(0.01)
