ENGR 1222 — Engineering Problem Solving III
Overview
Instructor of Record — Louisiana Tech University Spring 2026 · Sections 002 and 006 1 term · 49 students · 2 lecture sections
ENGR 1222 is the third course in Louisiana Tech’s Living with the Lab (LWTL) first-year engineering sequence, which integrates hands-on problem solving, fabrication, and professional development from the first week of study. I delivered lectures to two sections — meeting four hours per week per section — covering the full course curriculum alongside the course coordinator team.
The course culminates in an open-ended design project in which student teams apply sensors, microcontroller programming, and fabrication skills to solve a self-defined engineering problem.
Topics

|---|---|---|
| Circuit fundamentals & sensors | Engineering design process | Technical communication |
| Arduino microcontroller programming | Laser-cut nameplate fabrication | Engineering format homework |
| Robotics kit integration | SolidWorks (CAD) | Engineering economics |
| Troubleshooting & debugging | Extruded aluminum structures | Global & societal issues in engineering |
| Selected math & science topics | Design project development | Professional development activities |
Hands-On Activities
Arduino & Robotics Kit Students build on the Arduino microcontroller and robotics kit used in ENGR 120 and 121, implementing sensors and devices for a final open-ended design project. All programming activities require hardware demonstrated at the start of class — Arduino ready, circuitry assembled, program uploaded.
Sensors, Devices & Fabrication Each student purchases a kit with sensors and materials for a fabrication activity. Students design a personal nameplate in CAD, cut it on the prototyping lab’s laser cutter, and mount it on a stand constructed from extruded aluminum.
Design Project Teams complete an open-ended engineering design project integrating the sensors, programming, and fabrication skills developed throughout the quarter. The project counts for 20 % of the course grade and is presented formally at the end of term.
Professional Development Students are required to attend four approved professional development events during the quarter — including professional society meetings, engineering college service hours, and invited technical talks.
