The GPIO.BOARD option specifies that you are referring to the pins by the number of the pin the the plug - i.e the numbers printed on the board (e.g. P1) and in the middle of the diagrams below.

The GPIO.BCM option means that you are referring to the pins by the "Broadcom SOC channel" number, these are the numbers after "GPIO" in the green rectangles around the outside of the below diagrams:

Unfortunately the BCM numbers changed between versions of the Pi1 Model B, and you'll need to work out which one you have guide here. So it may be safer to use the BOARD numbers if you are going to use more than one Raspberry Pi in a project.

#GPIO
# 3.3v = 1,17, 5.0v =2,4 GND = 6,9,14,20,25,30,34,39
# my LED is on Pin 3 and Ground is on Pin 6
import RPi.GPIO as GPIO
from time import sleep # import time library 
GPIO.setmode(GPIO.BOARD)
myOutLED = 3
myInputSwitch = 5
GPIO.setup(myOutLED, GPIO.OUT)
GPIO.setup(myInputSwitch, GPIO.IN)
while True :
    inputState = GPIO.input(myInputSwitch)
    print(inputState)
    if inputState == False:
        print('button pressed')
        photoCounter=4
        while (photoCounter > 0):
            GPIO.output(myOutLED, True)
            print('  LED ON')
            sleep(1)
            GPIO.output(myOutLED, False)
            print('  LED OFF')
            sleep(1)
            photoCounter=photoCounter-1

GPIO.cleanup()

Open LAB  and/or Robot Club 

• LAB - Duration: 60 Min
• Link: Robot Club Google Sites
• Instructions & Expectations: Connect with your Robot Club Team.  You will either be working on your Robot Project or an Open Lab Project.  
• You will need to account for your time. You will need to convince me by your form submission that you worked given the time allotted. 
• If  you or your Robot Club Team worked on the Robot Club project, you will make sure your Robot Project Status Google docs are updated.  
• If you worked on an Open Lab Project, you will also need to tell me about what you accomplished and what you are planning next.
• How to Submit Assignment:   Each Student needs to account for your time.  
• Every One Do The Following: Turn in an Open Lab Blog Post
• If you also worked on your Robot Club Project, also UPDATE your Robot Project Status Google docs.  
• Dig Deeper: Open Lab:
• Robot Club Google Sites
• Guest LED Lesson
• Printers - Work on taking the printers apart
• TinkerCAD
• Udemy - My Courses (specifically the Arduino Workshop and Electronics Engineering Technology class)

Clean Up

• Assignment - Duration: 2-10 Min
