Hi Dave

Thanks for the last 2 replies and the encouragement

I looked at what you had changed in my code and I think its making sense to me , however

I tried compiling it and it failed

Part of your code said

architecture Counter of Led_Blink is
signal count : unsigned(27 downto 0); 
signal q_out : std_logic(3 downto 0);       **** This is the line the compiler comlains about 

however Quartus claims , Error (10380): VHDL error at Led_Blink.vhd(21): std_logic type is used but not declared as an array type

and I dont know enough to know why its telling me this

It's a typo -- the signal q_out should be declared as a std_logic_vector(3 downto 0);
