ARead sensor, convert value to string, then use lcd.write_string()
BDirectly pass sensor integer value to lcd.write_string()
CUse lcd.cursor_pos to read sensor data
DChange I2C address to sensor address before displaying
Step-by-Step Solution
Solution:
  1. Step 1: Understand data types for display

    Sensor values are usually numeric and must be converted to strings for display.
  2. Step 2: Use lcd.write_string() with string data

    Convert sensor reading to string, then call lcd.write_string() to show it.
  3. Final Answer:

    Read sensor, convert value to string, then use lcd.write_string() -> Option A
  4. Quick Check:

    Convert sensor data to string before display [OK]
Quick Trick: Convert numbers to strings before lcd.write_string() [OK]
Common Mistakes:
MISTAKES
  • Passing integers directly to write_string
  • Misusing cursor_pos for reading data
