[Solved] Identify the error in this code that tries to set LED brightness: from gpiozero import PWMLED led = PWMLED(18) led.brightness(0.7) | Raspberry Pi

Raspberry Pi - gpiozero Library

Identify the error in this code that tries to set LED brightness:

from gpiozero import PWMLED
led = PWMLED(18)
led.brightness(0.7)

AUsing parentheses after brightness instead of assignment

BWrong pin number for PWMLED

CMissing import for time module

DPWMLED does not support brightness control

Step-by-Step Solution

Solution:

Step 1: Check how brightness is set
Brightness is an attribute, so it should be assigned a value, not called like a function.
Step 2: Verify other options
Pin 18 is valid, time module is not needed here, and PWMLED supports brightness.
Final Answer:
Using parentheses after brightness instead of assignment -> Option A
Quick Check:
brightness is attribute, not method = D [OK]

Quick Trick: Set brightness with =, not parentheses [OK]
