Raspberry Pi - Platform

You want to build a project that lights up an LED when you press a button connected to your Raspberry Pi. Which hardware ports will you use to connect the LED and button, and how will you see the output on a screen?

AConnect LED and button to Ethernet port; use USB for screen output

BConnect LED and button to GPIO pins; use HDMI port for screen output

CConnect LED and button to HDMI port; use USB for screen output

DConnect LED and button to USB ports; use GPIO pins for screen output

Step-by-Step Solution

Solution:

Step 1: Identify connection for LED and button
LEDs and buttons are electronic components controlled via GPIO pins on the Raspberry Pi.
Step 2: Identify how to display output
The HDMI port connects the Raspberry Pi to a screen to show output visually.
Final Answer:
Connect LED and button to GPIO pins; use HDMI port for screen output -> Option B
Quick Check:
GPIO for electronics + HDMI for display [OK]

Quick Trick: Use GPIO for electronics, HDMI for screen display [OK]

Common Mistakes:

Connecting electronics to USB or HDMI ports
Using USB for screen output
Confusing Ethernet port with GPIO
