I cannot get the timing to work correctly(using tic and toc), I cannot get my while ~(B|R|Y|G) to work, which i need it to reiterate 4 times before it BOOM!, Last, need help with making a sound that makes 3 sharp beeps. Thanks!

tic
switch input('Will you cut the (R)ed, (Y)ellow,(B)lue, or (G)reen wire?-->','s')
    %while ~(B|R|Y|G)
        %input('Try Again -->');
    case 'R'
        bomb = 'DISARMED';
    case 'Y'
        bomb = 'BOOM!';
    case 'B'
        bomb = 'BOOM!';
    case 'G'
        tElapsed = toc;
    %if (tElapsed>5)
            %bomb = 'BOOM!';
    end
        tic
        switch input('Will you cut the (R)ed, (Y)ellow, or (B)lue wire? -->','s')
            case 'R'
                bomb = 'DISARMED';
            case 'Y'
                bomb = 'BOOM!';
            case 'B'
                bomb = 'BOOM!';
            otherwise
                bomb = 'BOOM!';
                tElapsed = toc;
        end
    otherwise
        bomb = 'BOOM!';
        if (tElapsed>5)
            bomb = 'BOOM!';
        end
end
%if bomb = ('DISARMED')
%load handel
      %sound(y,Fs);
%else 
  %beep;beep;beep;

I think you have placed the time counter toc at wrong place. You have to place toc at every case...then only time elapsed will be calculated.

@Snooping Poppet: it is not appreciated when you edit away the text of your question. Imagine if everyone did that, then this entire forum would be useless for anyone else as it would only consist of thousands of threads all reading "This post was taken down". Would you find that useful?

By deleting your question you unilaterally decided that my volunteered time helping you shall not be useful to anyone else. Do I get a say in this decision? Do you think this is why we volunteers come here and write our advice and comments?

If you want a consulting service then you will find plenty of them on them internet. This is a community forum with answers provided by volunteers.

Have a play around with this, you can change the logic very simply:

lim = 5;
arm = true;  % is armed.
xpl = false; % is exploding.
txt = 'Will you cut the (R)ed, (Y)ellow,(B)lue, or (G)reen wire? ';
tic
while arm && ~xpl
    switch upper(input(txt,'s'));
        case 'R'
            arm = false;
        case {'Y','B'}
            xpl = true;
        case 'G'
            xpl = toc>lim;
        otherwise
            disp('Try again!')
    end
end
if xpl
    load handel
    sound(y,Fs)
elseif ~arm
    beep
    beep
    beep
end

Note that using tic and toc is not the same as running a timer object.
