the prototyping area (Figure D-7). In the schematic, the other lead of the resistor is
connected to not one, but two other component terminals.
photoresistor and capacitor both share this connection. On the breadboard, the other
resistor lead is plugged into one of the rows of 5 sockets. This row also has leads from
the capacitor and photoresistor plugged into it. In the schematic, the other terminals of
the photoresistor and capacitor are connected to Vss. Here is a trick to keep in mind
when building circuits on a breadboard. You can use a wire to connect an entire row on
the breadboard to another row, or even to I/O pins or power terminals such as Vdd or
Vss. In this case, a wire was used to connect Vss to a row on the breadboard. Then, the
leads for the capacitor and photoresistor were plugged into the same row, completing the
circuit.
