5. Insert a set of one 10 microfarad and one 0.1 microfarad capacitor
   between the + voltage bus and the ground bus next to the V+ input for
   the decoder IC. Do the same for the inverter IC and the H-bridge IC, as
   shown in Figure 11-28.
   These capacitors filter out electrical noise introduced to the + voltage
   supply for each IC by the DC motors.


6. Insert wires to connect each component and terminal to the ground
   bus (marked with a – on this breadboard) and insert a wire to connect
   the two ground buses, as shown in Figure 11-29.

The resonator in the center of the three leads is the ground lead.
