Raspberry Pi - Platform
Which GPIO pin numbering mode is commonly used in Raspberry Pi LED blink programs?
AGPIO.NUMBER - random pin numbers
BGPIO.PIN - logical pin numbers
CGPIO.MODE - mode pin numbers
DGPIO.BOARD - physical pin numbers
Step-by-Step Solution
Solution:

  1. Step 1: Identify pin numbering modes

    Raspberry Pi GPIO library supports GPIO.BOARD and GPIO.BCM modes.

  2. Step 2: Common mode for beginners

    GPIO.BOARD uses physical pin numbers on the header, making it easier to follow.

  3. Final Answer:

    GPIO.BOARD - physical pin numbers -> Option D

  4. Quick Check:

    Pin numbering mode = GPIO.BOARD [OK]
Quick Trick: Use GPIO.BOARD for physical pin numbers [OK]
Common Mistakes:
  • Using non-existent modes
  • Confusing BCM with BOARD
  • Assuming random numbering
