Here is the code that I'm using with Arduino. The code seems alright and the wiring on the Arduino seems okay as well, but I don't know where to place a speaker on the Arduino. The biggest problem is that the program doesn't run like I coded. After I uploaded this code to Arduino, the water pump just keeps running forever. Can anyone check up my code to make this run properly?

I am trying to make an automated watering system using an Arduino.

Here is my wiring diagram: And here is my circuit wired up:
