'------------------------- "Ticking bomb" picaxe 08M game --------------------- 
' Pick up the small box and you will hear a ticking sound - could it be a bomb. 
' Perhaps it would be wise to pass the box to someone else as soon as possible, 
' act quickly or you may hear the mornfull sounds of the death march playing.
' On the other hand you may hear the familiar sound of the Looney Tunes Theme.
' What should I do? is it wise to push the button for another dice with death.

'                         Detailed "Ticking Bomb" notes
'-------------------------------------------------------------------------------
' Holding the push button while switching the unit on will select "Loony Tunes".
' Switching unit on without holding the push button on will select "Death march" 
' When switched on the program cycles automatically by-passing the push button. 
' This mode also adds a ticking sound - repeated each second just like a clock.
' The program selects a dice number between one and six - a six "plays music".
' Each cycle,the random number program has a one in six chance of playing music. 
' Low dice numbers are shown on LED 0 and high dice numbers are shown on LED 1.
' To prevent a short game - the tune will not play during the first four cycles.
' To prevent a long game - the tune will always play after the twelfth cycle.
' Playing of any sound - either music or the beep sound - will make Led 2 flash.
' Once the tune has played the program will pause - push the button to continue.
' I have kept the music short,longer tunes can be used check,the picaxe web site.  
' You may exit the "ticking bomb" game at any time by turning the main switch off.
