Our experiment can be resume as :

when Button is clicked a message start is sent to the program.
when the program receives  (start) , digital 13  receives the signal through the buzzer 
which emits  a beep sound for 1 sec  and stop for 1 sec for 5 times  
then change the beep sound with the delay time at 0.5 sec  for also 5 times.
again change it at 0.1 sec for  11 time so and so ...
etc...
Till the total repeating time has elapse.
while the program is executing if  the key s is press the program stop
when a is press again start  is broadcast to the program.
