How do I make the turret on my tank rotate and the gun barrel move up and down using arrow keys?

I do not have any scripts regarding this, but I do understand that Cframe can be used to rotate the turret. I tried everything from ripping scripts from other models and putting it into my turret, but nothing happens. I would appreciate it if someone responds to this. Also, My tank uses the ATS chassis, I don't know if that conflicts with any scripts but I would like an answer to that aswell.
