You want to send sensor data from Arduino to Raspberry Pi over UART and log it. Which Python code snippet correctly reads lines continuously and prints them?

hard🚀 Application Q8 of 15

Raspberry Pi - Serial UART Communication

Awhile True: line = ser.readline() if line: print(line.decode().strip())

Bfor i in range(10): print(ser.read(10))

Cline = ser.read() print(line)

Dser.write(b'Start') print('Logging started')

Step-by-Step Solution

Solution:

Step 1: Identify continuous reading method
Using while True with readline() reads lines continuously.
Step 2: Decode and strip for clean output
Decoding bytes and stripping newline gives readable sensor data.
Final Answer:
while True: line = ser.readline() if line: print(line.decode().strip()) -> Option A
Quick Check:
Continuous read with decode and strip = while True: line = ser.readline() if line: print(line.decode().strip()) [OK]

Quick Trick: Use readline() in a loop and decode output for UART data [OK]

Common Mistakes:

MISTAKES

Using read() without loop
Not decoding bytes
Writing instead of reading
