Connecting the 7-Segment LED Display to the BASIC Stamp
Figure 6-10 shows the schematic and Figure 6-11 shows the wiring diagram for this
BASIC Stamp controlled 7-segment LED display example.
√
Build the circuit shown in Figure 6-10 and Figure 6-11.
Schematic and pin map: If you are trying to build the circuit from the schematic in Figure 6-
10 without relying on Figure 6-11, make sure to consult the 7-segment LED display’s pin
map (Figure 6-2, page 166).
