RPi.GPIO library setup in Raspberry Pi - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to import the RPi.GPIO library with the common alias.

Raspberry Pi

import [1] as GPIO

Drag options to blanks, or click blank then click option'

ARPi.GPIO

Bgpiozero

CGPIO

💡 Hint

Common Mistakes

Using 'gpiozero' instead of 'RPi.GPIO' which is a different library.

Trying to import 'GPIO' directly without the full library name.

The RPi.GPIO library is imported using import RPi.GPIO as GPIO to allow easy access with the alias GPIO.

Complete the code to set the GPIO numbering mode to BCM.

Raspberry Pi

GPIO.setmode([1])

Drag options to blanks, or click blank then click option'

AGPIO.BCM

BGPIO.BOARD

CGPIO.OUT

DGPIO.IN

Attempts:

💡 Hint

Common Mistakes

Using BOARD mode when BCM mode is required.

Passing direction constants like OUT or IN instead of mode.

Setting the mode to GPIO.BCM tells the library to use the Broadcom chip's pin numbering.

Fix the error in the code to clean up GPIO settings at the end.

GPIO.[1]()

Drag options to blanks, or click blank then click option'

Bclear

Ccleanup

Dreset

💡 Hint

Common Mistakes

Using 'clear' or 'reset' which are not valid methods.

Forgetting to call cleanup causing warnings on next run.

The correct method to reset GPIO pins is GPIO.cleanup(). Other options do not exist or cause errors.

hard

Fill both blanks to set up a GPIO pin 18 as an output.

Raspberry Pi

GPIO.setup([1], [2])

Drag options to blanks, or click blank then click option'

A18

BGPIO.OUT

CGPIO.IN

D17

Attempts:

3 left

💡 Hint

Common Mistakes

Using pin 17 instead of 18.

Setting pin as input instead of output.

Pin 18 is set as an output using GPIO.setup(18, GPIO.OUT).

5fill in blank

hard

Fill all three blanks to set pin 23 as input with a pull-up resistor.

Raspberry Pi

GPIO.setup([1], [2], pull_up_down=GPIO.[3])

Drag options to blanks, or click blank then click option'

A23

BGPIO.IN

CPUD_UP

DGPIO.OUT

Attempts:

3 left

💡 Hint

Common Mistakes

Using GPIO.OUT instead of GPIO.IN for input pin.

Using PUD_DOWN instead of PUD_UP for pull-up resistor.

Pin 23 is set as input with a pull-up resistor using GPIO.setup(23, GPIO.IN, pull_up_down=GPIO.PUD_UP).
