Used in conjunction with the Arduino Duemilanove ProtoShield prototype expansion board, the circuit is used to build a prototype, can be directly soldered components on the board, you can also connect the above mini bread board circuit
Bread boards and circuit board through the double-sided adhesive connection, sold bread board and board are separate
ProtoShield prototype expansion board with two buttons and two LED circuits can be used directly, all of the pins and power leads are ideal for building a circuit and Arduino with a prototype
