[Solved] Identify the error in this code snippet for controlling LED brightness:import RPi.GPIO as GPIO GPIO.setmode(GPIO.BCM) GPIO.setup(17, GPIO.OUT) pwm = GPIO.PWM(17, 1000) pwm.start(110) | Raspberry Pi

Raspberry Pi - PWM Output

Identify the error in this code snippet for controlling LED brightness:

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)
pwm = GPIO.PWM(17, 1000)
pwm.start(110)

AMissing GPIO.cleanup() call

BDuty cycle value 110 is invalid (must be 0-100)

CPWM frequency 1000 is too low

DGPIO pin 17 is not set as output

Step-by-Step Solution

Solution:

Step 1: Check duty cycle range
Duty cycle must be between 0 and 100; 110 is invalid and causes error.
Step 2: Verify other code parts
Pin 17 is set as output; frequency 1000 Hz is valid; cleanup is optional here.
Final Answer:
Duty cycle value 110 is invalid (must be 0-100) -> Option B
Quick Check:
Duty cycle range = 0-100 [OK]

Quick Trick: Duty cycle must be 0 to 100 percent [OK]
