02Goals

What we set out to do.

01

Build a self-contained device that monitors and displays ambient temperature in real time as a first electromechanical engineering project.

02

Learn the fundamentals of sensor interfacing, microcontroller programming, and enclosure design through hands-on building.

03

Produce a polished, functional prototype that demonstrates understanding of the full design-to-build process.

03My contribution

What I did.

Contribution

Solo Build

  • Sole designer and builder — responsible for all hardware, code, and enclosure from start to finish.
  • Wrote the Arduino sketch for sensor reading, rolling-average smoothing, and formatted LCD display output.
  • Designed and 3D printed the enclosure in TinkerCad with ventilation slots for accurate ambient sensing.
