Story

I added Mind Control to my previous Automated Beer Pong game!

Using an EEG Headset (used MindFlex headset game purchased on Ebay for ~$12), HC-06 Bluetooth chip, and good old Arduino, the project came to life.

Concept, build, and demonstration video.

Once the Bluetooth transceiver is wired in and the device is paired to a computer, the Brainwave OSC software breaks the incoming data up into separate attention and meditation charts. A second program, Processing, runs a code that grabs the attention levels from Brainwave OSC. In the Processing code there is also a variable Attention threshold that once broken, sends an "on" signal to the connected Arduino. The Arduino then moves the cups at the users' selected speed.

Brainwave OSC Software by Trent Brooks.

Attention levels displayed on Processing software, majority of code by Andre Le.

Processing Software Code

Change the float threshold = __; to adjust when the computer sends a signal to the Arduino through the COM port on line 18.

// Import the libraries and dependencies
import oscP5.*;
import java.awt.*;
import processing.serial.*;

Serial myPort;
String myText="";

OscP5 oscP5;
Robot pong;
float currentAttention;
float threshold = 70;

// The setup function runs once when you start your application
void setup(){
    
    size(300,300);
    myPort = new Serial(this, "COM6", 57600);
    myPort.bufferUntil('n');
  
  oscP5 = new OscP5(this, 7771); // Start listening for incoming messages at port 7771 
  
  try { // Try and create a new robot named bob
    pong = new Robot();
  } 
  catch (AWTException e) { // If there is an error, print it out to the console
    e.printStackTrace();

  }
}

void serialEvent (Serial myPort) {
  myText = myPort.readStringUntil('n');
}

// The draw function runs over and over again until you close the application
void draw(){
  
  background(0,0,0);
  text (myText, 120, 120);
  myText="";
  
  if (currentAttention > threshold) {
    //bob.keyPress(java.awt.event.KeyEvent.VK_ENTER);
    myPort.write("on");
    delay(7000);
    
  }
 // else {
    //bob.keyRelease(java.awt.event.KeyEvent.VK_ENTER);
  //}
  
}

void oscEvent(OscMessage theMessage) {
  // Print the address and typetag of the message to the console
  // println("OSC Message received! The address pattern is " + theMessage.addrPattern() + ". The typetag is: " + theMessage.typetag());

  // Check for Attention messages only
  if (theMessage.checkAddrPattern("/attention") == true) {
    currentAttention = theMessage.get(0).floatValue();
    println("Your attention is at: " + currentAttention);
  }  
}

Updated Arduino Code

This is the code with added serial port monitoring, when the Arduino receives "on" through the serial port, it runs the cups back and forth at defined speed.
