Unity 2d: in game button that can be activated by player

I have spent a lot of time searching for my answer and couldn't find it anywhere, so i'm asking here: How can i make in fame button that can be pressed when the player is near that button? I assume that i would need some kind of trigger on player that will detect button triger, i tried doing so and got stuck, so if anyone would explain how i can do it with examples i will be very thankful!and sorry for my bad english
