On the breadboard is a must that set up as a switch the game to the MOSFET comes from the busy hands on another MP3 player. When had gained goes high the MOSFET ports 5 V power to the MP3 player that is shown in this image. That player automatically starts and place the sound on the ST card in a mini MP3 player.
The MOSFET switches shown on a breadboard so that you can see how to make one yourself. We also have circuit boards set out to make this very easy. A link to that circuit boar is below this provided. Click here.
