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.

Code

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.

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.
