Pablo Guerra has produced a super fun mashup of a brain based EEG (Backyard Brains) and circuit bent musical feedback (DjckO).

When Pablo Closes his eyes, alpha power increases, which causes the digital potentiometer to drop from95 kilohms to 70 kilohms. This then modulates a sound generation circuit in Pablo’s Musical Instrument

If you would like to build this, you must

1. Remove LEDs 3,4, and 6 from the Heart and Brain SpikerShield (two yellow LEDs, and last red LED). This is because we are using those pins now to talk to the Digital Potentiometer.
2. Upload this new code to your Arduino that allows the SpikeRecorder software to talk to the Digital Potential
3.  Run our new SpikeRecorder Software Prototype
