Getting Started with Python for the Internet of Things

How to do it...

1. Create a script called tilt.py to report the state of the tilt switch:

#!/usr/bin/python3 
#tilt.py 
import RPi.GPIO as GPIO 
#HARDWARE SETUP 
# GPIO 
# 2[===========T=]26[=======]40 
# 1[=============]25[=======]39 
#Tilt Config 
TILT_SW = 24 
 
def tilt_setup(): 
  #Setup the wiring 
  GPIO.setmode(GPIO.BOARD) 
  #Setup Ports 
  GPIO.setup(TILT_SW,GPIO.IN,pull_up_down=GPIO.PUD_UP) 
 
def tilt_moving(): 
  #Report the state of the Tilt Switch 
  return GPIO.input(TILT_SW) 
 
def main(): 
  import time 
  tilt_setup() 
  while True: 
    print("TILT %s"% (GPIO.input(TILT_SW))) 
    time.sleep(0.1) 
 
if __name__=='__main__': 
  try: 
    main() 
  finally: 
    GPIO.cleanup() 
    print("Closed Everything. END") 
#End 

2. You can test the script by running it directly with the following command:

sudo ...
