The effect of the moon (and to a lesser extent the sun) is to cause two bulges in the earth -- on the side facing the moon and the side opposite the moon. So as the earth turns, places move through two bulges per rotation, i.e., twice a day.

I can understand the moon's gravitational pull. But how does the Sun come into picture?

The sun's effect on tides is about half that of the moon. When sun & moon are aligned (full moon or new moon) the tides are larger because their respective bulges coincide and reinforce each other. When they're perpendicular (half moon) the bulges are more distributed around the earth, resulting in lower tides.
