soldering up your circuit. Therefore, in lots of experiments, it is often used as a hub to connect
two or more devices.
Normally, there are two types of breadboard: full+ and half+. You can tell their difference
from the names. A half+ breadboard is half the size of a full+ one and their functions are the
same. Here take the full+ breadboard.
(s) Full+
(t) Half+
This is the internal structure of a full+ breadboard. Although there are holes on the
breadboard, internally some of them are connected with metal strips. Those holes are to
insert pins of dev ices or wires. As show n in the fig. (t) below , there are four long metal strips
on the long sides; the blue and red lines are marked just for clear observation. But you can
take the blue line as the GND and red one as VCC for convenience. Every five holes in the
middle are v ertically connected with metal strips internally which don’t connect with each
other. You can connect them horizontally with wires or components. A groov e is made in the
middle on the breadboard for IC chips.
