Complete the code to turn on an LED connected to GPIO pin 17.

Raspberry Pi

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)
GPIO.output(17, [1])

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

💡 Hint

Common Mistakes

Using GPIO.LOW which turns the LED off.

GPIO.HIGH turns the LED on by sending voltage to the pin.

Fix the error in the code to read a button press on GPIO pin 18.

Raspberry Pi

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, [1])
if GPIO.input(18):
    print("Button pressed")

💡 Hint

Common Mistakes

Setting the pin as output instead of input.

GPIO.IN sets the pin as input to read button presses.

4fill in blank

hard

Fill both blanks to create a dictionary of GPIO pin states for pins 22 and 23.

Raspberry Pi

pin_states = {22: GPIO.[1], 23: GPIO.[2]

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

💡 Hint

Common Mistakes

Using IN or OUT which are pin modes, not states.

GPIO.HIGH and GPIO.LOW represent the on/off states of pins.

Fill all three blanks to set up GPIO, turn on pin 24, and clean up.

Raspberry Pi

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.[1])
GPIO.setup(24, GPIO.[2])
GPIO.output(24, GPIO.[3])
GPIO.cleanup()

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

💡 Hint

Common Mistakes

Using IN instead of OUT for setup or LOW instead of HIGH for output.

BCM sets pin numbering, OUT sets pin as output, HIGH turns pin on.
