Raspberry Pi - GPIO Basics with Python

AGPIO.setup(10, GPIO.OUT) GPIO.setup(11, GPIO.IN)

BGPIO.setup(10, GPIO.IN) GPIO.setup(11, GPIO.IN)

CGPIO.setup(10, GPIO.IN) GPIO.setup(11, GPIO.OUT)

DGPIO.setup(10, GPIO.OUT) GPIO.setup(11, GPIO.OUT)

Step-by-Step Solution

Solution:

Step 1: Determine pin roles
Pin 10 reads button input, so it must be input mode.
Step 2: Set LED pin mode
Pin 11 controls LED output, so it must be output mode.
Final Answer:
GPIO.setup(10, GPIO.IN) GPIO.setup(11, GPIO.OUT) -> Option C
Quick Check:
Input pin for button, output pin for LED [OK]

Quick Trick: Input for button pin, output for LED pin [OK]
