How do you correctly set the GPIO pin numbering mode to BCM in a Python script using RPi.GPIO?
easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Identify correct method
The method to set pin numbering mode is GPIO.setmode().Step 2: Use correct constant
GPIO.BCM is the constant for BCM numbering mode.Final Answer:
GPIO.setmode(GPIO.BCM) -> Option AQuick Check:
setmode with BCM constant sets BCM numbering [OK]
Quick Trick: Use GPIO.setmode(GPIO.BCM) to select BCM mode [OK]
Common Mistakes:
- Using GPIO.setup instead of setmode
- Using incorrect constants like PHYSICAL
- Calling GPIO.mode which does not exist
