<p>A building block includes: a brick, at least one pair of conductive pieces, a circuit board and a base. The brick includes at least one pair of studs projected from a top thereof. A stud hole penetrates through each stud. Each stud hole has only one conductive piece disposed therein. The conductive piece has an insertion electrode, a contact electrode and a connection electrode. The conductive piece is pressed against the brick by itself or by an insulating piece. The circuit board is pressed against the contact electrode of the conductive piece, the base is pressed against the circuit and the base is fixed in the brick. The circuit board includes a positive electrode circuit and a negative electrode circuit respectively contacted with the at least one pair of the conductive pieces and a functional unit electrically connected with both electrode circuits.</p> |
