1N4001 diode

This diode supplies optional power from the Arduino external power jack to the amplifier IC. This allows you to produce more audio output power when you connect a higher voltage source to the Arduino external power jack. You can connect up to 18 volts to the power jack, and hence to to the amplifier. The diode is marked with a bar on one end that must be placed according to the board diagram.
