Control the Flame of a Candle Using Your Focus (EEG)

A brain-computer interface project that uses EEG beta waves to control a virtual candle flame's brightness in real-time based on your concentration level, using Chords Web visualization.

Firmware:Arduino
Use Cases:Education

Overview

This creative neurofeedback project lets you manipulate a virtual candle's brightness by concentrating. The system reads EEG beta waves from your prefrontal cortex and provides real-time visual feedback through the Chords Web application.

Hardware Required

  • BioAmp EXG Pill
  • Brain BioAmp Band (optional, can use gel electrodes)
  • BioAmp Cable v3
  • Arduino Uno R4 Minima (or Raspberry Pi Pico)
  • Jumper cables
  • Nuprep Skin Preparation Gel

How It Works

EEG signals are captured from the forehead, amplified by the BioAmp EXG Pill, and processed through the Chords Arduino Firmware. The Chords Web application visualizes the data and includes interactive applications like the candle flame that responds to your mental focus.

Software

  • Chords Arduino Firmware (board-specific versions available)
  • Chords Web for visualization and interactive applications

What You'll Learn

  • Neurofeedback basics and real-time brain signal visualization
  • Using Chords Web for BCI applications
  • Understanding beta wave correlation with focus and attention
