Making the circuit...............................................................................

Time to go one-on-one with your breadboard. Here are the steps involved:

1. Place the LM555 IC, the LM4017 IC, and six terminal blocks on the
   breadboard, as shown in Figure 10-7.

The six terminal blocks in this figure will be used to connect two wires

each to various components in the circuit. The wires from one terminal

block go to the battery pack, and the wires from each of the other termi-

nal blocks go to one of the LED/resistor arrays.

2. Insert discrete components on the breadboard, as shown in Figure 10-8.
