The Board of Education
Figure 1-6 shows the remaining circuit symbols used in the first experiment and where to
find them on the Board of Education. The symbol for Vdd is the positive 5 volt supply for
the BASIC Stamp and the Board of Education. There are 4 sockets along the top side of
the breadboard to the left for making connections to Vdd.
Next, the ground symbol is used for Vss. This is the reference terminal for taking
measurements, and it's considered to be 0 volts compared to all other voltages on the
Board of Education. The four sockets for connecting jumper wires to Vss along the top of
the breadboard to the right.
There is a row of fifteen sockets along the left side of the breadboard for connecting to
the BASIC Stamp I/O pins. Each I/O pin has a label. I/O pin P0 is connected to the
bottom left socket. Pin P1 is the next socket up, and above that socket is the connection to
pin P2, and so on through pin P15 at the top left.
IMPORTANT: Disconnect the Board of Education's power source while you build the circuit.

LM358 op-amp
The circuit symbol has numbers
on each of its terminals that
correspond to the numbers on
the block diagram.
The block diagram is a top-view
of the part from your parts kit
with the circuit symbols for the
two op-amps in the part drawn in.
Make sure to note the location of
pin 1 and the index mark when
you place the LM358 on the
breadboard. Improper wiring can
damage an op-amp.
