When you start building your circuit, make sure to check it against the schematic symbol
and part drawing. For the part drawing, note that the LED’s leads are different lengths.
The longer lead is connected to the LED’s anode, and the shorter lead is connected to its
cathode. Also, if you look closely at the LED’s plastic case, it’s mostly round, but there
is a small flat spot right near the shorter lead that that tells you it’s the cathode. This
really comes in handy if the leads have been clipped to the same length.
LED Test Circuit Parts
(1) LED – Green
(1) Resistor – 470 Ω (yellow-violet-brown)
Building the LED Test Circuit
You will build a circuit by plugging the LED and resistor leads into small holes called
sockets on the prototyping area shown in Figure 2-5. This prototyping area has black
sockets along the top and along the left. The black sockets along the top have labels
above them: Vdd, Vin, and Vss. These are called the power terminals, and they will be
used to supply your circuits with electricity. The black sockets on the left have labels
like P0, P1, up through P15. These are sockets that you can use to connect your circuit to
the BASIC Stamp module’s input/output pins. The white board with lots of holes in it is
called a solderless breadboard. You will use this breadboard to connect components to
each other and build circuits.
Identifying the parts: In addition to the part drawings in Figure 2-2 and Figure 2-4, you can
use the photo on the last page of the book to help identify the parts in the kit needed for this
and all other activities. For more information on the parts in this photo, see Appendix B:
Equipment and Parts Lists.
