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 a function named Buzz() def Buzz(numTimes,speed): for i in range(0,numTimes):## Run loop numTimes print "Iteration " + str(i+1)## Print current loop GPIO.output(7,True)## Switch on pin 7 time.sleep(speed)## Wait GPIO.output(7,False)## Switch off pin 7 time.sleep(speed)## Wait print "Done" ## When loop is complete, print "Done" GPIO.cleanup() ## Ask user for total number of buzzes and length of each blink iterations = raw_input("Enter total number of times to buzz: ") speed = raw_input("Enter length of each buzz(seconds): ") ## Start Buzz() function. Convert user input from strings to numeric data types and pass to Buzz() as parameters Buzz(int(iterations),float(speed)) |
