Traffic Light Doorbell
The first time anyone presses the button a green light turns On and plays a nice melody. This way the user will know the bell worked.
Usually the bell is pressed twice after sometime waiting, this is Ok and the Doorbell will tell the user that it worked, but a warning color and tone will be given to the user.
This is the final notice, the user will now have to wait 5 minutes until he/she can press the button and get a signal. (a warning red color and angry tone will be given to the user).
