Brainding – Circuit Bending Using an EEG

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


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
