I'm a newbie in this field, i have a problem and i hope that you all can help me.  

i wanted to add in countdown timer into the music box that shown at fpga4fun but i have no idea on how to do the coding for the countdown timer, so i need your help. :( i hope that the countdown timer is in VHDL code or you all can give me the VHDL coding and i'll try to change the music box verilog code so that i can add in the VHDL code. The countdown timer that i want is when i turn on the music box it will countdown 5 second, after countdown it will start to play music.  thanks you very much for your help :)

Are you using a dev. board? What is the frequency of the fpga clock? The timer is based on the clock period. The code looks like: 

 entity....  architecture arch of ent_name is  begin  process(rst, clk)  begin  if(rst='1') then  cont_reg <= ( others=>'0');  elsif(clk'event and clk='1') else  cont_reg <= cont_prox;  end if;  end process;   cont_prox <= cont_reg + 1 when ( cont_reg < timeout ) else  cont_reg;   start <= '0' when ( cont_reg < timeout ) else  '1';  end architecture arch;  The signal "start" goes up to '1' when expires the timer. you enable the circuit with this signal. The constant timeout depends of clock period.
