What will happen if you connect a keyboard to the Raspberry Pi's USB port?
AThe keyboard will work and allow typing input
BThe keyboard will control GPIO pins directly
CThe keyboard will display output on the HDMI screen
DThe keyboard will charge the Raspberry Pi
Step-by-Step Solution
Solution:

  1. Step 1: Understand USB port function

    USB ports connect input devices like keyboards and mice to the Raspberry Pi.

  2. Step 2: Analyze keyboard behavior

    When connected, the keyboard sends typing input to the Raspberry Pi; it does not control GPIO or display output.

  3. Final Answer:

    The keyboard will work and allow typing input -> Option A

  4. Quick Check:

    USB port = input device connection [OK]
Quick Trick: USB ports connect input devices like keyboards [OK]
Common Mistakes:
  • Thinking keyboard controls GPIO pins
  • Assuming keyboard shows output on HDMI
  • Believing keyboard charges the Pi
