The three terminal blocks shown in this figure will be used to connect

two wires each to various components in the circuit. The wires from

these terminal blocks go to the battery pack, IR LED, and potentiometer,

respectively.

2. Insert wires to connect the IC and the terminal blocks to the ground
   bus (marked with a – sign on this breadboard) and insert a wire
   between the two ground buses to connect them to each other, as
   shown in Figure 9-8.

Three shorter wires connect components to the ground bus; the long

wire on the right connects the two ground buses.

3. Insert wires to connect the IC and the terminal block for the battery
   to the +V bus, as shown in Figure 9-9.


4. Insert wires to connect the IC, terminal blocks, and discrete compo-
   nents, as shown in Figure 9-10.


5. Insert discrete components on the breadboard, as shown in
   Figure 9-11.

Note that the shorter of the LED leads is inserted in the ground bus.
