We use Past Simple:

- when we talk about an action which started and finished in the past. We use such words as: last week/year, yesterday, 2 days ago, ect.;

- some regular, usual action in the past;

- listing of action in the past.

We use Present Perfect:

- when we talk about an action which has connection with present;

- when we should describe our life experience and some facts;

- when we talk about results;

- when the action started in the past and now has not finished yet. In this case we use the words "for", "since".
