In this course, you are going to build an amplifier to play music from your smartphone, your computer, or other similar music sources.

This amplifier is one of the easiest amplifiers to build because you don’t need a lot of components. It has a good amount of volume and very little noise.

First, you’re going to build it on a breadboard, to make sure the parts you are using are suitable. Then, you’ll solder it onto a prototyping board.
