Abstract: An electronic building block set with a metal layer on the outer surface of each building block includes a main and an auxiliary building block. The top of the main building block includes plural main hollow posts, each with a main sensing contact, and has a main metal layer on the outer surface. The main sensing contacts and the main metal layer are electrically connected to opposite-polarity main electrode circuits respectively. The bottom of the auxiliary building block includes a first sensing element and has an auxiliary metal layer on the outer surface. The first sensing element and the auxiliary metal layer are electrically connected to opposite-polarity auxiliary electrode circuits respectively. When the building blocks are engaged, the first sensing element is electrically connected to the corresponding main sensing contact, and the auxiliary metal layer, to the main metal layer to enable electricity or signal transmission between the building blocks.
