Focus & Spin: Design Your Own Brainwave Display

NeuroMaker STEM

Using the attention data from your NeuroMaker BCI headset, you’ll control a servo motor and bring a custom-built dial to life. As your attention levels rise and fall, the motor will rotate a pointer, giving you a real-time, physical display of your brain’s focus.

This project blends engineering and creativity. You’ll not only wire up and code your own motor system, but also design the look and feel of your attention dial using simple materials like cardboard or paper plates. Think of it as your first brain-powered gadget—built and designed by you.

By completing this project, you’ll create your first motion-based BCI circuit. In other words, you’ll use brain data to control physical movement, all through a circuit you wired, coded, and designed yourself.

Project Duration

Approximately 90-120 minutes

Group Size

1–2 students per kit

Necessary Supplies

Items We Already Have or Used Previously:
- One NeuroMaker BCI Unit
- One SG90 Servo Motor (available in the NeuroMaker BioSensor Kit)
- A computer with Chrome browser and the Arduino IDE installed
New Items Needed for This Project
- One Arduino Uno board (requires purchase)
- One USB cable for the Arduino (usually included, but confirm or purchase separately)
- Three male-to-male jumper wires (requires purchase)
- Cardboard or another sturdy material for building the dial background
- Drawing materials (e.g., markers, scissors, double-sided tape or glue)
