hard📝 Application Q15 of 15

Raspberry Pi - Platform

AUse a web browser to turn the LED on and off

BWrite Python code that only prints messages without hardware control

CUse a Python library like RPi.GPIO to control the hardware pins

DConnect the LED to a smartphone and control it remotely

Step-by-Step Solution

Solution:

Step 1: Identify how to control hardware on Raspberry Pi
Raspberry Pi uses libraries like RPi.GPIO to interact with physical pins and devices like LEDs.
Step 2: Evaluate options for controlling an LED
Only Use a Python library like RPi.GPIO to control the hardware pins describes using a Python library to control hardware pins directly.
Final Answer:
Use a Python library like RPi.GPIO to control the hardware pins -> Option C
Quick Check:
Hardware control = Python + GPIO library [OK]

Quick Trick: Use GPIO library to control hardware pins in Python [OK]
