Raspberry Pi - PWM Output
Which method is used to create a PWM instance on a GPIO pin using
RPi.GPIO?Which method is used to create a PWM instance on a GPIO pin using RPi.GPIO?
easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Recall RPi.GPIO PWM creation syntax
The correct method to create a PWM object isGPIO.PWM(pin, frequency).Step 2: Verify other options
Other options likestartPWM,setPWM, orenablePWMdo not exist in RPi.GPIO.Final Answer:
GPIO.PWM(pin, frequency) -> Option AQuick Check:
Method to create PWM = GPIO.PWM(pin, frequency) [OK]
Quick Trick: Use GPIO.PWM(pin, freq) to create PWM instance [OK]
Common Mistakes:
- Using non-existent methods like startPWM
- Confusing method names with other libraries
- Forgetting to specify frequency
