Introduce the team and give brief roles?

2. Background Dr. Cantrell’s research HELLO!
Background: Describe what your project is and why you are building it. If additional information is required for your audience to understand your project, it should be presented now.
Box diagram below picture

3. Background
Combines the utility of an x-ray viewing light box with the ability to change colors
GUI => Microcontroller => LEDs

HELLO!
Design Process
Broke the project into two parts: hardware and software that could be tackled separately due to the even split between EE and CS majors
Hardware – built small scale prototypes with various arrangements of LEDs and researched optics for optimal color mixing
Software – built smaller programs for simple communication with the Arduino, for example, specifying one red, green, and blue value and lighting one LED

5. Architecture GUI µC LEDs 2 main components HELLO!

7. Architecture – Hardware (Circuitry)
HELLO!
Architecture – Hardware (Circuitry)
Digital System
We used an Arduino microcontroller that we programmed to accept integers from the GUI representing different duty cycles
15 Pulse Width Modulation (PWM) output pins on the Arduino were used to illuminate 5 tri-colored LEDs
- explain simply what a microcontroller is and what PWM is using the picture

9. Architecture – Hardware (Physical)
HELLO!
Architecture – Hardware (Physical)
Diffuser Plate
Also mention that the Arduino and wiring is beneath the pcb board
Trapezoidal shape - built with angled walls in order to allow the box to be positioned differently based on how it is being use
Diffuser plate on top to mix the light illuminating from within
Circuitry is installed at the bottom (Arduino at based with the LED grid on top)

11. Architecture – Software (LightBox GUI)
HELLO!
Architecture – Software (LightBox GUI)
Programmed in the Python programming language
Allows the user to manipulate the intensity of each of the LEDs within the LightBox
Sends signals in the form of 8 bit integers to the microcontroller
- The 8 bit integers are representations of various duty cycles (as Garrett explained)

12. Architecture – Software (LightBox GUI)
HELLO!
Architecture – Software (LightBox GUI)
- The layout of the LEDs in the GUI is an exact mapping to the LEDs inside the box

13. Enjoy! Demonstration HELLO!
Demonstration: Provide a demo of our working product. For practical reasons, this may need to take the form of a video. If your product is not working, demonstrate it as best as you can.

14. Issues No major issues A few minor ones… Time Management
HELLO!
Issues
No major issues
A few minor ones…
Time Management
Circuit (Sockets)
Confusing Arduino documentation
Issues: Describe major setbacks or threats to your project that you have experienced and talk about how you dealt with them.

15. Conclusion Development process went smoothly Hardware Requirements
HELLO!
Fantastic!
Conclusion
Development process went smoothly
Hardware Requirements
Complete!
Software Requirements
The Light Box is simple for anyone to use and is able to produce a wide variety of colors
Dr. Cantrell, our client, is very happy with the final product
Dr. Cantrell
Conclusion: Recap your main points and provide a sense of closure to your presentation.

16. Any Questions? Any Color Requests?
