Project-Infinity

Google Phone

  • Project Infinity is a mind controlled rover which is made using arduino and is controlled by Neurosky Mindwave Headset with the help of an app.

Required Materials

  1. BreadBoard - Half Size
  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. EEG WAVES

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.
