Bachelor Project

University project functioning as direct predecessor to the bachelor thesis

An ESP based project to generate and record audio as a stimulus towards functional biometric authentication.

Usability Requirements

To run the project sketch on an ESP32-based microcontroller it has to be flashed onto the controller memory. For now the project is only tested using a Heltec Wifi Kit 32. The installation instructions for this controller into the arduino environment can be found here.

Additional requirements to run microphone or speaker are already given in the code of the sketch. As speaker any mylar speaker can be used.

Wiring of the Components

How the different components are wired can be taken from the following schematic:

Usage

To use the set-up project to conduct audio recordings the following steps are needed:

1. Add your WiFi credentials to the arduino sketch using the parameters ssid and password in the main sketch
2. Flash the sketch to the micro controller
3. Connect to the IP-address shown on the controllers display using a web browser
4. Play and record audio audio files using the buttons of the shown web site
