Now that we have discussed all the basics of the Brain wave along with the introduction of Brain wave sensor, it’s time to move onto the subsequent topics. In this article, we will see how the Brain wave chip works, what should be the expected algorithm inside the sensor and what should we do to make such a sensor on our own with any micro controller or processor.
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.
Now that we know the basics of Brainwaves and the sensor on which we are working, it’s time to learn about the brain of this brain wave sensor. The main part of any device is its processing part and in the case of Mindflex Sensor, it’s the NeuroSky EEG Chip.Let’s move on to the details so as to know what the chip contains and how does it work.
Till now we have seen the working of the EEG chip and we are also aware of our sensor. So now it is the time to do some experiments and gain some practical knowledge on brain waves.In this first experiment, we will try to hack the EEG signals. For this, we need to make some arrangements so that we can easily measure the signals.
Brain wave is a common term that can be easily found in Science books/newspapers or can be heard from doctors and researchers. Have you ever thought what exactly Brain waves are? How are they produced? What is their role in day-to-day life and how do they affect us?Let me take you through a roller coaster ride exploring Brain Waves alongside its features, types, characteristics, and other details. Brain Wave is among the few technologies the world is researching these days. There are a lot of potential techniques in this field and it may solve many of our future problems.
