Which component is essential to control multiple LEDs individually on a Raspberry Pi?
AA monitor connected to the Raspberry Pi
BA USB keyboard
CAn internet connection
DGPIO pins configured as outputs
Step-by-Step Solution
Solution:

  1. Step 1: Identify how LEDs are controlled

    Each LED needs a GPIO pin set as output to turn it on or off individually.

  2. Step 2: Evaluate the options

    Only GPIO pins configured as outputs can control LEDs. The other options are unrelated to LED control.

  3. Final Answer:

    GPIO pins configured as outputs -> Option D

  4. Quick Check:

    LED control needs GPIO outputs = True [OK]
Quick Trick: Use GPIO pins as outputs for LEDs [OK]
Common Mistakes:
  • Confusing input pins with output pins
  • Thinking internet controls LEDs
  • Assuming peripherals control LEDs
