Visualize EEG, EOG, EMG, ECG using

[@MayureshPitale-c3y]

hey dude I went through your work its amazing but I'm not able to record EEG signals with my exg pill and esp32 could you help me with arduino code?

[@UpsideDownLabs]

This issue can be because the minimum voltage required to use BioAmp EXG Pill is 5V. How to resolve the issue? It's not recommended but to resolve this issue you can use external 5V supply for sensor, Use common ground and create a resistor divider to convert the higher voltage output of the sensor to a lower voltage level so as to make it compatible with the development board. This step is crucial to prevent the sensor from harming the analog pins of the development board. Please share an email on [e-mail] with the connections you have made and we will help you the resolve the issues asap.

Hi Deepak. I read somewhere that the max sample rate for EXG pill is 125Hz. What limits its sampling? Can we not sample it at a higher rate with a more powerful ADC / Microcontroller?

[@UpsideDownLabs]

Hey, please share the resource if you have read that somewhere. The sampling rate depends on the microcontroller development board you are using. For example, the sampling rate for Arduino Uno R3 is 250 by default but it can be changed in the code as well.

[@razorr1920]

@@UpsideDownLabs Got my EXG pill today. Used it with Uno (original) and sample code was EOG filter. The waveform was way too fast and I could understand nothing. Tried with no adapter to the laptop and out in the garden. No good.

[@UpsideDownLabs]

Hey, we are assuming that you are using Arduino IDE v2.0 in which the serial plotter plots less data points in a single frame so it feels like it is moving fast. We recommend you to use Arduino IDE v1.8.19 (Legacy IDE) in which the serial monitor plots more data points in a single frame so you will be able to visualise the EOG signals easily. In case of any more queries, please email us on [e-mail] and we will be happy to help you out :)

The signal is so clean. Loving it😍

[@UpsideDownLabs]

It really is! Thanks 😊

[@AleksaZ]

Incredibly useful, connections and bandpass info all in one place! Great job!

[@UpsideDownLabs]

Glad you liked it!

[@panigrahi_industries]

Incredible watching Indian engineers break through. just eye opening. well, I got a question about whether eeg input pins can be increased for a thorough eeg dataset construction. Afterall im astounded by this project looking forward.

[@UpsideDownLabs]

Thanks a lot Premansh for your kind words. We think with more EEG inputs you are talking about more number of channels. So BioAmp EXG Pill is a single channel biopotential amplifier but you can use multiple of them to make a multi channel EEG acquisition system. store.upsidedownlabs.tech/product/bioamp-exg-pill/ We do provide a 6 channel Brain BioAmp Band or EEG band as well that can simultaneously record EEG data from the prefrontal cortex and visual cortex. store.upsidedownlabs.tech/product/brain-bioamp-band-2/

[@PallabDas-o4f]

This is a good video, but how to store this data as a numbers of stream in a csv or text file format for further analysis & classification? Please make a video on this.

[@UpsideDownLabs]

Thanks a lot! It's pretty easy. You just click the record button on the top right corner of Spike Recorder to record the data in .wav file and then you can convert it into any other format (.csv, .txt, etc) as per your project requriements.

[@nidhinppramod6326]

How could i use these wave patterns convert to a numerical table which i could use it for prediction and Ml modelling

[@UpsideDownLabs]

On the top right corner of Spike Recorder, there is a record button. Using that you can directly record the data in .wav format and then convert it into CSV format or any other format of your choice.

[@kamal_kumar19k]

I'm beginner, so please tell me can we determine meditation and attention with this module using Arduino

[@UpsideDownLabs]

BioAmp EXG Pill is a single channel biopotential sensor that can help you record the EEG signals but it totally depends on how you are using it for meditation or measuring parameters like attention, focus, concentration, etc. You can give it a try using BrainBay software.

[@GdncHfjbdkf]

The elctrode patch can use infrared sensors on the ahort infrared low spectrum light to have the least amount of radiation i have been exposed to this spectrum for 20 years i think its okay if your exposure is least like hours or even a year

[@tahayousaf3275]

Hi, Great video! Sorry but I am new to all this. How accurate is the EEG signal being received and displayed? Do you need to filter out the signal using any additional components? Lastly, I have normally seen people having two reference electrodes, is just using one going to decrease the performance? Thank you.

[@UpsideDownLabs]

The EEG signal is of publication grade quality. You don't need any additional components to filter out the signal. Just make sure to disconnect the charger from your laptop and sit 5 metres away from any AC device for better signal acquisition. Let us know how it went for you ✨

[@UpsideDownLabs]

Hey, Which microcontroller board are you using? We have seen that backyard brains software does not work with all the microcontroller boards. Please try using Arduino Uno R3 and it should work properly. Still in case of any more queries, please mail us at [e-mail] and we will be happy to help you :)

[@GdncHfjbdkf]

Try to decode your temporal eeg info but you can transform the electrodes into infrared that way the eeg signal will reach the basi ganglia

[@prajeetbohara4816]

you think it's possible to take these waves data and use in Arduino to control the pins. So that I can use these brain signals to control servos or other device? EMG feature of your device can do it but I wanna make sure if we can do the same with EEG feature too?

[@UpsideDownLabs]

Hey Prateek, We have not tried controlling servo motor using EEG but one of the student created a project where he was controlling a car game in laptop using EEG. Complete tutorial for the project is on instructables: www.instructables.com/Controlling-Video-Game-Using-Brainwaves-EEG/

[@prajeetbohara4816]

@@UpsideDownLabs I'm on the verge of finding a really affordable brain sensor that can translate brain signals into digital signals so that anyone with no or surface understanding of biomedical engineering or EEG can incorporate the brain waves in their project and we can advance the concept of BCI to a wider audience. Other EEG sensors are comparatively high. You guys are amazing, this startup and product is amazing. I will order the kit and try to figure out this EEG sensor with Arduino. Meanwhile, if you guys come up with something that can be used to control the microcontroller pins using this EEG please please do let everybody know. Thanks!

how to connect the cable to bioamp exg pill ! show us a tutorial

[@UpsideDownLabs]

All the circuit diagrams for electrode placements, connecting BioAmp EXG Pill to ADC (like Arduino) and connecting BioAmp EXG Pill to BioAmp Cable are already given in the video itself. Let us know if you need something specific.

[@analprakashsharma3026]

what kind of electrodes are required? Dry or Gel based. Are electrodes reusable?Also what is the voltage range of output signal I will get when using bioamp candy?

[@UpsideDownLabs]

You can either use Gel electrodes which should be used only once or BioAmp Bands that have Dry electrodes which are washable and reusable.

[@UpsideDownLabs]

The output voltage swings around the VCC/2 so for 5V you'll see the voltage swing around 2.5V. the exact output voltage is dependent on EMG strength.

How to see these Graphs on Arduino Serial Plotter rather than Spike Recorder. Which Part o the code we should change and what are the changes that Should be made ? I checked out the Github , but the codes in Github are not Working....So please Reply to this. Thank You

[@UpsideDownLabs]

Hey Rohit, You can check the link below for various Arduino Sketches. github.com/upsidedownlabs/BioAmp-EXG-Pill/tree/main/software You can directly flash the Arduino sketch and visualize the graphs on the serial plotter of Arduino IDE. If a particular code is not working then please check the steps below: 1. Check the baud rate is set as 115200 on the serial plotter 2. Input pin is set at A0 so make the connection accordingly If still the code does not work or the graph is not as per your expectation, then please email us at [e-mail] with the images and demo video so that we can help you in a better way.
