Programmable and beeping final countdown timer (with Arduino)

This video shows a beeping countdown timer created with Arduino Uno.
The number of seconds can be configured by clicking the (P) push-switch up to 9 seconds. The counting down will be shown in a 7-segment BCD.
There is another (S) push-switch to Start/Stop the timer.
If it reaches zero, it will make a long sound indicating the end of the pre-programmed time
On-board reset button will be used to reset the system (that way the time programmed can be changed)
