Digital sticky-note device

A portable touchscreen prototype integrating enclosure, electronics, firmware, and power.

Arduino C++ Enclosure design Electronics

My contribution

I developed a custom enclosure, integrated the display, microcontroller, and power source, and programmed the control behavior in C++. I tested the LiPo charging circuitry with thermal checks and documented wiring, issues, and revisions.

Outcome

Produced a working touchscreen note-taking prototype and prepared engineering review material. The project connected mechanical packaging with embedded programming and power-system testing.
