Hello Raspberry Pi

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


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
