Here is a more complex example that involves two additional parts, a photoresistor and a
capacitor. The schematic symbols and part drawings for these components are shown in
Figure D-5.
Since this schematic shown in Figure D-6 calls for a 220 Ω resistor, the first step is to
consult Appendix C: Resistor Color Codes to determine the color code for a 220 Ω
resistor. The color code is Red, Red, Brown. This resistor is connected to P6 in the
schematic, which corresponds to the resistor lead plugged into the socket labeled P6 in
