2. Arduino Uno R3
3. Hobby Motor - Geared
4. 1K Ohm Resistor
5. 9v Battery
6. USB Cable A to B
7. Jumper Wires Pack - M/M
8. Jumper Wires Pack - M/F
9. Neurosky Mindwave 2 Headset

Code

• The code can be found here.

Library Required

• This is the library for the Adafruit Motor Shield V2 for Arduino. It supports DC motors & Stepper motors with microstepping as well as stacking-support.

Working Principle

• Brain waves are oscillating electrical voltages in the brain measuring just a few millionths of a volt. There are five widely recognized brain waves, and the main frequencies of human EEG waves are listed below along with their characteristics.

Working

• Meditation produces alpha waves (frequency range: 7.5-12.5 Hz).
• Attention produces beta waves (frequency range: 12.5-30 Hz).
• So by isolating these 2 frequencies in brainwaves, App can trigger the right signals to control the rover.
• The EEG headset records the brainwaves.
• The brainwaves are analyzed on the app to isolate the right frequencies.
• The app is connected to an Arduino microcontroller via Bluetooth. The Arduino gets a specific input for each frequency detected.
• Through those inputs it changes its direction.
