The red arrow on the left points where the Brush Tool is to be found. When you click it a flyout opens and you can see where it is to be found.
Now look at the top panel. You can again see the 'Brush'. The '13' is the size. Click where the red arrow points to and it will reveal a drop down box.
Here is the drop down box. The Master diameter sets the size of the brush tip. Note the slider just below it. It is to decrease and increase the size of the brush tip. The 'Hardness' determines how hard or soft the strokes will be. There is also a slider below it. When you drag it to the left or the right the hardness changes.
Note the three arrows. The red arrow points to a slider which you can lower and raise to see the brushes available in a set. The light blue arrow points to hard brush tip and the green to a soft brush tip which is thinner that the hard brush.
The red arrow and the white hand points to a no 19 brush (note the number on the left beside the brush). You must click to select a brush. Let me click it.
Here is a hard brush stroke. Try it out.
Now I am choosing a soft brush.
Here is a soft brush stroke. Try it out.
Now look at the Opacity of the brush. It is set a 100 %. Raising and lowering the opacity of the brush is needed sometimes. The blue arrow points to a slider which reduces and increases the opacity.

I have lowered the opacity of the brush to 57 % as you can see.
Now to access the brush sets. Click on the 'Brushes' at the top right of Photoshop.
