STJLOL-DMU Basic GPIO

light.py

#the setup

import RPi.GPIO as GPIO   #lets you use GPIO
from time import sleep    #lets you use sleep(2) as a timer for the lights

GPIO.setmode(GPIO.BOARD)  #tells the program what labeling system to use

GPIO.setup(17, GPIO.OUT)  #tells the pi exactly what number pin you'll be using


#the code

GPIO.output(17, GPIO.HIGH) #tells the pi to turn on this pin
sleep(2)                   #waits 2 seconds
GPIO.output(17, GPIO.LOW)  #tells the pi to turn off this pin


#the cleanup

GPIO.cleanup()             #shuts down all GPIO stuff
