Final Demo


The Final Demonstration is the single most important measure of the success of your project. The evaluation is focused on issues of completion, testing, and reliable operation. You will demo your entire project to a team of one professor, your TA, and several peer reviewers. Other guests (e.g., alumni, high school students, donors) may, at times, also be present.

Requirements and Grading

Students must be able to demonstrate the full functionality of their project and any requirement in their Requirements and Verification table to the instructor. Credit will not be given for features which cannot be demonstrated. For tests that are lengthy or require equipment not available at the demo, students should have their lab notebooks ready to show testing data. For any portion of the project which does not function as specified, students should have hypotheses (and supporting evidence) of what is causing the problem.

The design team should be ready to justify design decisions and discuss any technical aspect of the project or its performance (not just one's own responsibilities). Quantitative results are expected wherever applicable. See the Demo Grading Rubric for specific details, but in general, show the following:

  1. Completion: The project has been entirely completed.
  2. Thoroughness: Care and attention to detail are evident in construction and layout.
  3. Performance: Performance is completely verified, and operation is reliable.
  4. Understanding: Everyone on the project team must must be able to demonstrate understanding of his/her technical work and show that all members have contributed significantly.
  5. Complexity: A multiplier will be applied to your score reflecting the complexity of the project. This multiplier is between 0.5 and 1.

Submission and Deadlines

Sign-up for a demo time is handled through the PACE system. Again, remember to sign up for a peer review, as well.

Link to the idea:


The Donor Wall on the southwest side of first floor in ECEB is to celebrate and appreciate everyone who helped and donated for ECEB.

However, because of poor lighting and color contrast between the copper and the wall behind, donor names are not noticed as much as they should, especially after sunset.

Solution Overview:

Here is the image of the Donor Wall:

We are going to design and implement a dynamic and interactive illuminating system for the Donor Wall by installing LEDs on the background. LEDs can be placed behind the names to softly illuminate each name. LEDs can also fill in the transparent gaps in the “circuit board” to allow for interaction and dynamic animation.

And our project’s system would contain 2 basic modes:

Default mode: When there is nobody near the Donor Wall, the names are softly illuminated from the back of each name block.

Moving mode: When sensors detect any stimulation such as a person walking nearby, the LEDs are controlled to animate “current” or “pulses” flowing through the “circuit board” into name boards.

Depending on the progress of our project, we have some additional modes:

Pressing mode: When someone is physically pressing on a name block, detected by pressure sensors, the LEDs are controlled to

animate scattering of outgoing light, just as if a wave or light is emitted from that name block.

Solution Components:

Sensor Subsystem:

IR sensors (PIR modules or IR LEDs with phototransistor) or ultrasonic sensors to detect presence and proximity of people in front of the Donor Wall.

Pressure sensors to detect if someone is pressing on a block.

Lighting Subsystem:

A lot of LEDs is needed to be installed on the PCBs to be our lighting subsystem. These are hidden as much as possible so that people focus on the names instead of the LEDs.

Controlling Subsystem:

The main part of the system is the controlling unit. We plan to use a microprocessor to process the signal from those sensors and send signal to LEDs. And because the system has different modes, switching between them correctly is also important for the project.

Power Subsystem:

AC (Wall outlet; 120V, 60Hz) to DC (acceptable DC voltage and current applicable for our circuit design) power adapter or possible AC-DC converter circuit

Criterion for success:

Whole system should work correctly in each mode and switch between different modes correctly. The names should be highlighted in a comfortable and aesthetically pleasing way. Our project is acceptable for senior design because it contains both hardware and software parts dealing with signal processing, power, control, and circuit design with sensors.
