easy📝 Conceptual Q2 of 15
Raspberry Pi - Platform
What is the main purpose of the GPIO pins on a Raspberry Pi?
ATo connect and control electronic components
BTo connect USB devices like keyboards
CTo output video signals
DTo provide internet connection
Step-by-Step Solution
Solution:

  1. Step 1: Understand GPIO function

    GPIO pins allow the Raspberry Pi to interact with electronic parts like LEDs, sensors, and motors.

  2. Step 2: Differentiate from other ports

    USB ports connect peripherals, HDMI outputs video, Ethernet provides internet, so these are not GPIO functions.

  3. Final Answer:

    To connect and control electronic components -> Option A

  4. Quick Check:

    GPIO pins = electronic control [OK]
Quick Trick: GPIO pins control hardware parts like LEDs [OK]
Common Mistakes:
  • Mixing USB with GPIO
  • Thinking GPIO provides internet
