🧪 First Project Idea – Blink an LED with Python

🔧 Requirements:

• 1 LED
• 1 Resistor (470Ω)
• Breadboard + jumper wires

🔌 Wiring:

• GPIO18 → Resistor → LED → GND

🧠 Code:

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)

GPIO.output(18, GPIO.HIGH)
time.sleep(1)
GPIO.output(18, GPIO.LOW)

GPIO.cleanup()

🎯 This project teaches GPIO control using Python—your first step into physical computing.
