Which Python command correctly configures GPIO pin 18 as an output for controlling an LED on Raspberry Pi?
easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Identify setup function
GPIO.setup(pin_number, mode) sets pin mode.Step 2: Set pin 18 as output
Use GPIO.OUT to configure as output.Final Answer:
GPIO.setup(18, GPIO.OUT) -> Option BQuick Check:
setup() with GPIO.OUT sets output pin [OK]
Quick Trick: Use GPIO.setup(pin, GPIO.OUT) for output pins [OK]
Common Mistakes:
- Using GPIO.IN instead of GPIO.OUT
- Calling GPIO.output() to set mode
- Misusing GPIO.setmode() for pin setup
