Presently, I am thinking of changing something depending on my attention and meditation level, say the brightness of a small LED. We will be controlling the brightness of an LED using the attention and meditation levels of our Brain at any particular time. We will be using Arduino UNO and mindflex sensor which we have chosen to read the brain wave and an LED to show the results. We are changing the brightness of the LED which can be easily controlled using PWM technique.
