Which Python code snippet correctly sets up GPIO pin 17 as an input for a button on Raspberry Pi?
Which Python code snippet correctly sets up GPIO pin 17 as an input for a button on Raspberry Pi?
easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Recall GPIO setup syntax
To set a pin as input, use GPIO.setup(pin_number, GPIO.IN).Step 2: Match the correct option
GPIO.setup(17, GPIO.IN) uses GPIO.setup(17, GPIO.IN), which is correct for input pin setup.Final Answer:
GPIO.setup(17, GPIO.IN) -> Option BQuick Check:
GPIO.setup(pin, GPIO.IN) sets input pin [OK]
Quick Trick: Use GPIO.setup with GPIO.IN for input pins [OK]
Common Mistakes:
- Using GPIO.OUT instead of GPIO.IN for input
- Confusing GPIO.input() with GPIO.setup()
- Trying to use GPIO.output() on input pins
