easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Recall correct parameter names in serial.Serial()
The correct parameters are 'baudrate' for speed and 'timeout' for wait time.Step 2: Match parameters with options
Only serial.Serial('/dev/ttyUSB0', baudrate=9600, timeout=1) uses 'baudrate=9600' and 'timeout=1' correctly.Final Answer:
serial.Serial('/dev/ttyUSB0', baudrate=9600, timeout=1) -> Option CQuick Check:
baudrate and timeout are correct parameters [OK]
Quick Trick: Use 'baudrate' and 'timeout' keywords exactly [OK]
Common Mistakes:
MISTAKES- Using wrong parameter names like 'speed' or 'rate'
- Confusing timeout with delay
- Missing required parameters
