Project guidelines

                         

The project should take no longer than two weeks to complete.  Some students reported they did it all on a Saturday afternoon.

 

Choosing a project:

A good suggestion is that you choose a four bit mapping project for the first combinational project and a four bit sequencer for the second project.  Check with Dr. Phillips first to make sure you choice is at the right level of difficulty.

 

Media:

Recommend you use Microsoft Power point and provide a file for your demonstration, otherwise just hand write your slides onto transparencies that you provide.

 

Steps:

  1. Get on the schedule for showing your project.
  2. Write up your problem statement, and then convert your statement into design requirements. 
  3. Translate your problem statement into a truth table using the techniques shown in your notes.
  4. Provide a Karnaugh map for each output variable in your network.
  5. Show your minimum design from the Karnaugh outputs.  This step will vary slightly for those students using multiplexer devices.
  6. Draw out your circuit design.
  7. Build your circuit.
  8. Demonstrate your circuit.  Your briefing consist of:
    1. Item 1 and 2 on one slide 1.
    2. Item 3 and 4 on slide 2.
    3. Item 5 on slide 3.
    4. Leave slide 1 on screen while you show your circuit works.
    5. Demonstrate you circuit to all students, answer any questions.

 

Dr. Phillips will not help you debug your circuit.  This is part of your experience to be gained.

You will receive 100 points after you have completed step 8.e.  This is an “all or nothing” assignment.  Points are not awarded to projects that do not work.  Start early as there is no flexibility for partial credit for projects.

 

Have fun!

 

 

Notes:

Supportive things you need to learn is how the following devices work:

See manufacturer’s web sites for technical information of gate packages.

Understand how the Light Emitting Diodes (LED) works.

Understand how the linear 7805 voltage regulator works.

Understand the basic concept of a resistor.

Some of you will purchase packages that have open collector peculiarities.  When you find you gates don’t work as intended, you need to look for pull-up, or pull-down resistor peculiarities.

Finally, a zero input means the input has to be grounded.  A floating input (not connected) is not zero.
