Verifying the Digital Test Setup

Now that you have constructed the logic power supply, logic indicators, and digital input circuitry, the left half of your breadboard socket is pretty full. To check your layout, compare it with the figure below. The power supply busses are indicated, along with the connection points for the digital inputs and logic indicators. You'll be using these connections for all of your experiments with digital circuits.

The breadboard socket with testing circuits installed.

One circuit we will need later is a clock circuit. There are of course many ways to accomplish this, but an easy one for testing purposes is to use the power transformer secondary winding as a basic source. Such a circuit will actually fit in the empty columns between the LED indicator input resistors. We'll add that circuit when we reach experiments that will require it.

At this point, you are ready to begin performing your experiments. For any group of experiments, be sure to perform them in the order listed at the top of the page, since some experiments build up circuits started in a preceding experiment. The link given at the bottom of each experimental page will always take you to the next experiment in the sequence.
