Embedded product study / physical inputs, firmware, wireless interface, and enclosure

Overview

A compact wireless input-device prototype combining custom embedded behavior, physical controls, and enclosure development.

Problem

A purpose-built input device requires electronics, firmware, interaction behavior, and physical form to be developed as one coherent product rather than isolated parts.

Proposed Solution

The prototype integrates physical inputs with an ESP32-C3 firmware layer and a purpose-built enclosure to explore a complete device workflow.

System Architecture

A functional flow, not a decorative diagram.

This conceptual view communicates the primary system boundaries represented by the current prototype.
