目录OverviewBuild a music box here! You can play the music files in the TF card, select the song with Joystic rocker and change volume. SchematicBy reading the analog value, you can detect and judgeg the Joystic's movement in the X-Y direction.At the same time, you can choose the control mode according to the stay time. Equipment
