Background
• Combines the utility of an x-ray viewing light box with the ability to change colors
• Assists in Dr. Cantrell’s research regarding color balancing
GUI => Microcontroller => LEDs

Architecture – Hardware (Circuitry)
Digital System We used an Arduino microcontroller that
we programmed to accept integers from the GUI representing different duty cycles
15 output pins on the Arduino were used to illuminate 5 tri-colored LEDs

Architecture – Hardware (Physical)
Physical LightBox Trapezoidal shape - built with angled walls
in order to allow the box to be positioned differently based on how it is being used
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)

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

Conclusion
Our development process went smoothly throughout the entire year
Hardware Requirements Complete!
Software Requirements Complete!
GUI => Microcontroller => LEDs The Light Box is able to produce a wide
variety of colors Our client, Dr. Cantrell, is very happy with
the final product
