The board is made of plastic with a matrix of holes. Wires and component leads can be pushed into
the holes to make appropriate connections. Each “hole” on the board contains a metal spring contact.
When a wire or component lead is pushed down into the hole an electrical connection is made with that
hole’s spring contact.
The breadboards provide an interconnection bet n holes on the board using metallic “bus”

t-in interconnections and the typical circuit board layout, some of the following
chniques are commonly used when working with a breadboard.
• A jumper wire can be used to connect the positive source lead to one of the horizontal buss
lines marked with a “plus” (+) sign.
• Another jumper wire can be used to connect the GND to one of the
ontal source connection row to the
appropriate point(s) in the circuit on the vertical bus line portion of the board.

connections made underneath the surface. The holes are internally connected so that each 50 hole
horizontal bus line is independent from the other and each small 5 hole vertical bus line is also
connected independently. Figure P-14 shows the internal connections of the holes on the breadboard.
