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
