EGR 314 challenges teams to create an interactive S.T.E.M. exhibit to teach K-12 students about a topic of the teams’ choosing. This team project tests middle-schoolers’ periodic table knowledge with the Element Sorter — a gamified, colorblind-friendly sorting machine that differentiates between a total of twenty-four metals, nonmetals, and metalloids. The device prompts users to…

This team project is a display of the STEM concept of electricity generation through means of a hydroelectric dam. The team utilized Arizona science standards to target the audience of students in grades 7–12. The team chose to use the hydroelectric dam because it is not common in the Arizona desert. A stepper motor was used…

The Human Interface Module is a compact embedded system designed to visualize input signals on an OLED display. Powered by a 12V DC input stepped down to 3.3V, it features an ESP32-S3 microcontroller for processing, ADS1115 for high-resolution analog-to-digital conversion, and SSD1306 for waveform display. User inputs are captured via tactile push-button switches, while onboard…

This team is developing an object following robot to help K-12 students learn more about control, sensing and communication in robotics. More specifically, this project will educate middle and high school students by highlighting the microprocessors, sensors, supporting components, technical limitations and technical capabilities of the robot. Through use of the robot, this project will…

Teams in this course are developing projects with STEM-themed displays that demonstrate a single scientific/engineering concept in an interactive, web-enabled, physical device while following standards and modularity. The intended users are K-12 students interested in learning about science, technology, engineering, or math. Sponsor

This team made a small centrifuge to display the relative differences in gravity on different planets and celestial bodies in the solar system. Sponsor

An interactive game was designed by this team as a museum-like exhibit to show K-12 students how physical hardware can be used to interact and affect digital signals in a circuit by allowing them to control the output of an OLED and actuator via a pushbutton interface. Sponsor

This project is a cooling system that utilizes three microcontrollers to manage different functions for improved performance and modularity. One microcontroller handles Wi-Fi connectivity and monitors ambient temperature using a sensor. The second microcontroller controls the fan adjusting based on inputs from users. The third microcontroller powers a user-friendly Human-Machine Interface (HMI), allowing users to…

This project is a simulated wind tunnel designed to provide an engaging and educational experience. Each member of this team is responsible for a unique subsystem. The Aircraft Pitch Controller adjusts a stepper motor based on user input. The Fan Airspeed Controller drives a DC motor to generate airflow. The User Input module captures operator…
