import RPi.GPIO as GPIO ## Import GPIO Library
import time ## Import 'time' library.  Allows us to use 'sleep'

GPIO.setmode(GPIO.BOARD) ## Use BOARD pin numbering
GPIO.setup(7, GPIO.OUT) ## Setup GPIO pin 7 to OUT

## Define function named Blink()
def Blink(numTimes, speed):
    for i in range(0,numTimes): ## Run loop numTimes
        print "Iteration " + str(i+1) ##Print current loop
        GPIO.output(7, True) ## Turn on GPIO pin 7
        time.sleep(speed) ## Wait
        GPIO.output(7, False) ## Switch off GPIO pin 7
        time.sleep(speed) ## Wait
    print "Done" ## When loop is complete, print "Done"
    GPIO.cleanup()

## Prompt user for input
iterations = raw_input("Enter the total number of times to blink: ")
speed = raw_input("Enter the length of each blink in seconds: ")

## Start Blink() function. Convert user input from strings to numeric data types and pass to Blink() as parameters
Blink(int(iterations),float(speed))
