easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Recall correct Python library and bus number
Python uses smbus library and bus 1 for Raspberry Pi's I2C.Step 2: Check code syntax and initialization
import smbus and bus = smbus.SMBus(1) is correct syntax.Final Answer:
import smbus\nbus = smbus.SMBus(1) -> Option BQuick Check:
Correct library and bus number = import smbus bus = smbus.SMBus(1) [OK]
Quick Trick: Use smbus.SMBus(1) to access I2C bus on Raspberry Pi [OK]
Common Mistakes:
MISTAKES- Using wrong bus number 0
- Importing non-existent i2c module
- Wrong class or method names
