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.

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.

Controlling Led brightness using Meditation and attention level (Part 5/13) https://www.engineersgarage.com/controlling-led-brightness-using-meditation-and-attention-level-part-5-13/ https://www.engineersgarage.com/controlling-led-brightness-using-meditation-and-attention-level-part-5-13/#respond Thu, 30 Jun 2022 12:05:50 +0000 http://engineersgarag-main/controlling-led-brightness-using-meditation-and-attention-level-part-5-13/  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.

Control Motor’s Speed using Meditation and Attention Level of Brain (Part 6/13) https://www.engineersgarage.com/control-motors-speed-using-meditation-and-attention-level-of-brain-part-6-13/ https://www.engineersgarage.com/control-motors-speed-using-meditation-and-attention-level-of-brain-part-6-13/#respond Thu, 30 Jun 2022 12:04:28 +0000 http://engineersgarag-main/control-motors-speed-using-meditation-and-attention-level-of-brain-part-6-13/  After controlling the brightness of LED with brain’s meditation and attention level, let’s move on to more applications on Brain Wave. Since the resolution in the earlier experiment was not clear, we will now try a different experiment to get a clearer picture.   In this article, I am again thinking of changing something which can give us a more clear understanding about the variations, say a DC motor. Here, we will control the speed of a motor using attention and meditation levels of our brain at any particular time.  We will be using Arduino UNO and mindflex sensor to read brain waves and a MOTOR to show the results.  We can also use an amplifier before the DC motor to see more variations in the speed.

How to determine whether a Person is sleeping through Brain waves (Part 7/13) https://www.engineersgarage.com/how-to-determine-whether-a-person-is-sleeping-through-brain-waves-part-7-13/ https://www.engineersgarage.com/how-to-determine-whether-a-person-is-sleeping-through-brain-waves-part-7-13/#respond Thu, 28 Oct 2021 15:52:04 +0000 http://engineersgarag-main/how-to-determine-whether-a-person-is-sleeping-through-brain-waves-part-7-13/ Previously in the Brain waves applications, we worked on controlling the speed of the motor using the attention level of the brain.  Now, it is time to check our study for some more real-time applications to detect if Brain wave can actually be used in day-to-day life or not. Presently in this article, I am planning to trigger something related to any type of Brain wave. In real life, often we may want to know if the patient (possibly our close one) is sleeping or not. So, I have tried to make a device using Brainwave through which I can find out if the person is sleeping   with the help of a message/call.

Servo Control using Brain Wave (Part 12/13) https://www.engineersgarage.com/servo-control-using-brain-wave-part-12-13/ https://www.engineersgarage.com/servo-control-using-brain-wave-part-12-13/#comments Wed, 17 Feb 2021 09:18:49 +0000 http://engineersgarag-main/servo-control-using-brain-wave-part-12-13/ After applying brainwaves to the RGB LEDs, now it is time to check extensions on some more real time applications and determine the efficiency as well as flexibility that can be achieved using this module. I am now planning to use it in some robotic field now. In this article, I am planning to make use of Brain Wave for some health applications along with robotics. While studying about robotic arms, I found that they are controlled by servo motor. What if we can control the servo motor using our Brainwave? I was not sure about this as the results of Brainwave are often random and I wanted to check if we can control the angle by our thoughts. So, to check the accuracy I gave it a try.

The results were good and we were able to see the variation in the form of brightness. Though we didn’t get much clear variation, we also performed a similar experiment using motor and changed the motor speed. Now let us try one more such experiment and this time we will change the colour of the RGB Led. Also, earlier we have used attention/meditation waves of e meters; this time we will use some of the Brain Waves to control the colour.

It would be really nice if we could see the variations of our EEG signals clearly in the form of some LED patterns so as to analyse how much variation it is producing by various thinking processes. Let’s get started.

This time I have tried to control an appliance using relay. Relay is just a switching device through which we can trigger both AC and DC appliance. Though it also depends on the maximum current that the relay can trigger and the total current our appliance needs.  I believe it will be nice to control home appliances just by thought and higher level of concentration. So let’s see more details about it.

Since meditation helps a person in many ways, I thought to give it a try and it proved to be very helpful.  However, while meditating I observed that I could not guess as to how well I am doing the meditation. As a result I decided to use brainwaves to develop a device which could inform me if I achieve a certain level. It can also be helpful for practitioners and meditators in future.
