The holes are connected together as follows:
• There are many columns of 5 holes each. The 5 holes within each column are electrically connected together, but the
columns are not electrically connected to each other. This makes 126 columns of 5 holes each. Note that “electrically
connected together” means that there is a wire within the breadboard connecting the 5 holes.
• All holes in the rows marked with a blue “–” or a red “+” are electrically connected together, but none of these rows are
electrically connected to each other. This makes 6 rows of 100 holes. The red “+” holes will usually be used for your “+”
battery or power supply connections and the blue “–” holes will usually be used for your ground (“–” battery or power
supply) connections.
Inserting Parts into the Breadboard: To insert components into the breadboard, keep their pins straight and gently push
into the holes. If the pins get bent and become difficult to insert, they can be straightened with a pliers. Always make sure
components do not touch each other.

Electrolytic capacitors have a positive
and a negative electrode. The negative
lead is indicated on the packaging by a
stripe with minus signs and possibly
arrowheads.
Warning:
If the capacitor is
connected with
incorrect polarity,
it may heat up and
either leak, or
cause the
capacitor to
explode.
