Raspberry Pi - GPIO Basics with Python
Which of the following is the correct way to set the GPIO pin numbering mode to use the physical pin numbers?
Which of the following is the correct way to set the GPIO pin numbering mode to use the physical pin numbers?
easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Recall pin numbering modes in RPi.GPIO
GPIO.BOARD uses physical pin numbers on the Raspberry Pi header, while GPIO.BCM uses Broadcom chip numbering.Step 2: Identify the correct constant for physical numbering
GPIO.BOARD is the correct constant for physical pin numbering. Other options are invalid or incorrect.Final Answer:
GPIO.setmode(GPIO.BOARD) -> Option CQuick Check:
Physical pin numbering = GPIO.BOARD = B [OK]
Quick Trick: Use GPIO.BOARD for physical pin numbers, GPIO.BCM for chip numbers [OK]
Common Mistakes:
- Using GPIO.BCM when physical pins needed
- Typing invalid constants like GPIO.PHYSICAL
- Confusing pin numbering modes
