Raspberry Pi Python exercise: Toggle LED on GPIO

Python example run on Raspberry Pi, to toggle GPIO pin for LED.

connection:

Example code, led.py:

import RPi.GPIO as GPIO
import time

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

while(True):
    GPIO.output(18, True)
    time.sleep(1.5)
    GPIO.output(18, False)
    time.sleep(0.5)

Run it with sudo:
$ sudo python led.py

Next:
- Change GPIO LED brightness with GPIO.PWM
