1. #Internet of Things with Python
   
2. 
   
3. This is the code repository for Internet of Things with Python, published by Packt. It contains all the supporting project files necessary to work through the book from start to finish.
   
4. 
   
5. ##Instructions and Navigation
   
6. 
   
7. The code included with this book is meant for use as an aid in performing the exercises and should not be used as a replacement for the book itself. Used out of context, the code may result in an unusable configuration and no warranty is given.
   
8. 
   
9. The code will look like the following:
   
10. class NumberInLeds:
    
11.     def __init__(self):
    
12.         self.leds = []
    
13.         for i in range(9, 0, -1):
    
14.             led = Led(i, 10 - i)
    
15.             self.leds.append(led)
    
16. 
    
17.     def print_number(self, number):
    
18.         print("==== Turning on {0} LEDs ====".format(number))
    
19.         for j in range(0, number):
    
20.             self.leds[j].turn_on()
    
21.         for k in range(number, 9):
    
22.             self.leds[k].turn_off()
    
23. 
    
24. 
    
25. if __name__ == "__main__":
    
26.     print ("Working with wiring-x86 on Intel Galileo Gen 2")
    
27. 
    
28.     number_in_leds = NumberInLeds()
    
29.     # Count from 0 to 9
    
30.     for i in range(0, 10):
    
31.         number_in_leds.print_number(i)
    
32.         time.sleep(3)
