What you are seeing in the picture above, is a button at the bottom that consists of conductive fabic on two sides of a spng that has holes cut in it. So, when u press the button, the two conductive fabrics touch each other and send a current through the conductive thread to the postivie and negativewires next to the arduino board. Once a button is pressed a tune plays and our LED at the top of the picture lights up.
