Abstract

Modeling with mathematics is an integral part of engineering, and therefore early exposure is ideal for engineering students. Hands on math modeling allows students to see why it is valuable. Additionally, immediate implementation of the model allows students to get instant feedback and success. To meet this demand, an activity was designed for students to build, model, program and test an LED display. These displays consisted of PCBs which contained 7 different colored LEDs and a resistor in series with each. Students were taught how to solder and constructed their circuits. Then students learned basic aspect of the Arduino programming language and made their light strip respond to simple situations such as button presses using if-else statements or timed intervals using loops. In order to be able to display dynamic data, students learned how to use an Arduino with an analog sensor, in this case a potentiometer, by having if-else statements create threshold values at which certain lights would turn on. Students are then tasked with writing a function to take in analog values and map them using an equation onto the LEDs. This task has students creating a system to monitor light levels. Students collect data using both a photometer and a photoresistor. Using the collected data, they are scaffolded through modeling by having them map specific values onto the data they have collected. They used linear regression and function transformation to accomplish this. Using this modeling skill, they also learn how to use Arduino libraries to interact with sensors that need them, such as ultrasonic sensors and create intelligent displays using these. Additionally, they experiment with other analog sensors, such as a hall effect and thermistor. This activity is designed to give students a practical introduction to the uses of math modeling in intelligent design practices and gives them the tools to implement sensor-based decision making into semester projects.
