An ESP32-powered Wi-Fi control interface for a hi-fi amplifier.

Overview

Built a wireless remote control system for a TDA7294-based hi-fi amplifier using an ESP32 and off-the-shelf components. The ESP32 hosts a web interface to control volume, input selection, and power from any device on the local network.

Engineering approach

An ESP32 provides local control: a browser acts as the interface while the microcontroller manages the amplifier’s input selection and volume. The project illustrates integration between hardware and an embedded web interface.

Scope and limitations

Personal project: design choices and long-term maintenance shape its evolution. This page describes documented capabilities rather than unmeasured results.
