Cornerstone of Engineering Water Contamination Display
An interactive exhibit for users to learn about sustainable water infrastructure topics.
For the Spring 2023 semester of Stacked Cornerstone of Engineering, we made a museum-style exhibit of a UN Sustainable goal, that uses Sparkfun components to teach an audience of children about the topic.
My group chose Goal #6: Clean Water, where we designed a 2-part display to visually tell a story to the viewers. Our first part of the display was a cup of food-coloring, suspended over a basic of clean water and attached to a stepper motor. The user then turns a potentiometer, that pours the food coloring into the basin of water. The user would then be able to watch as the food coloring spread throughout the entire water supply in front of them. The next part of the demonstration, with a paper straw, had a button the user could press that would pump water through the straw and slowly break it down, before it fell off the stand. The message of the demonstration was that water infrastructure, like any infrastructure, is susceptible to failure over time, but with water infrastructure in particular the effects of this are covert and deadly.
In this project my role was to take charge of the programming, assembly and testing of the exhibit apparatuses. This included desiging the circuits for the basin and pipeline displays, as well as building them. I programmed the Arduino and worked through several test circuits to find the best parameters and interface for the exhibit.
I researched and ordered the pumps we needed for the water-movement, and tested the systems used in our check-in presentations using an Arduino Uno. Additionally, when a water-pump broke down during the final presentation I was able to quickly diagnose and repair the issue.
