easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Check gpiozero TonalBuzzer constructor
The constructor takes the GPIO pin number as an integer, e.g., 17.Step 2: Validate syntax
UsingTonalBuzzer(17)is correct; keyword argumentpin=17is not standard, and strings like 'GPIO17' are invalid.Final Answer:
TonalBuzzer(17) -> Option AQuick Check:
Use integer pin number directly = A [OK]
Quick Trick: Use integer GPIO pin number without quotes [OK]
Common Mistakes:
- Passing pin as string instead of integer
- Using keyword argument pin=17 incorrectly
- Adding quotes around pin number
