- Insert wires to connect the ICs and the terminal blocks to the ground
bus and insert a wire between the two ground buses to connect them
to each other, as shown in Figure 8-6. - Insert wires to connect IC2 and the terminal block for IC2’s battery
pack to the +V bus, and a wire between the two +V buses to connect
them to each other, as shown in Figure 8-7.
Do not connect IC1 to the +V bus.If you do, you will probably fry the
poor IC because it isn’t designed to take 6 volts.- Insert wires to connect the ICs, terminal blocks for the coil (L1), vari-
able capacitor (C2) and terminal blocks for the potentiometer (R1),
and terminal block for the speaker and discrete components, as
shown in Figure 8-8. - Insert two 0.047 microfarad capacitors (C4 and C9), two 10 microfarad
capacitors (C6 and C7), one 100 microfarad capacitor (C8), two 0.001
microfarad capacitors (C1 and C3), one 0.1 microfarad capacitor (C5),
and one 10 ohm resistor (R2) on the breadboard, as shown in Figure 8-9.
When inserting electrolytic capacitors, be sure to check the schematic
to see where to insert the longer, positive (+) lead.
