Our experiment can be resume as :
 when '''Button''' is clicked, '''(start)''' is '''broadcasted'''.
 when the program receives  ('''start''') , the signal is received through'''digital 13''' , the buzzer then
 emits  a beep sound for '''1 sec'''  and stop for '''1 sec''' during '''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.
