19 *   
20 *   Connections to Arduino Uno/Nano:
21  *   
22 *   Connect a button to pin 12 (digital) and +5V (button Fire / Start)
23  *   Connect a 100 kohm resistor between pin 12 (digital) and GND
24 *   
25 *   If you want to use a Wheel, connect a 100 k ohm potentiomenter to: 
26 *           GND  (left pin), +5V (right pin), A0 (middle pin)
27 *           
28 *   If you wan  to use two buttons for left and right (like the original arcade)
29 *   Connect  two buttons to pin 4 and +5V (but.left), and pin 5 and +5V (but.right)
30 *   Connect  two 100 kohm resistors between pin 5 and GND, and pin 6 and GND*   
31 *   
32  *   TV composite out: 
33 *   Connect  1k ohm resistor from pin 9 to TV out (+)
34  *   Connect 470 ohm resistor from pin 7 to TV out (+)   
35 *   Connect GND                         to  TV out (-)
36 *   
37 *   Audio:
38 *   Connect a speaker between pin 11 and  GND
39 *   
40 *   Release history
41 *   
42 *  1.2 - added audio effects 
43  *      - added an option for using buttons or potentiometer 
44 *        to control  the cannon (see: #define USE_WHEEL) 
45 *      - emproved the size of the cannon  (you can go back to the   
46 *        old size changing cn1, cn2, cn3 with ca1,  ca2, ca3 
47 *        (look in the cannon section below)
48 *      
49 *  1.1  fixed some bugs 
50 *  1.0 initial release
