Mükemmel bir çalışma olmuş. Teşekkür ederim.
Ek number👍🏻👍🏻
Can I just connect it to a 7-9” monitor for visual effects?
How accurate and precise is this and how to increase the following properties
can i use limb lead rather than normal electrodes here ?
Signal is not shown connected adequately for the other option, yellow is switched with green, if not changed it shows heart attack high ST
Is there any way to make 12 lead?
How can I connect this ECG sensor with robotic hand ?
I actually did this project and everything went well till the end but i couldn't select the port u showed so we tried com3 but the heart waves are tooo fast and innacurate can u please help mw with this i actually need to submit this by dec 6th
Did you figure it out?
I made this project with your specification but my readings between the Q wave are erratic, can someone tell me why this happen and the possible solution? Thanks
It's either your connections are wrong or you are having cardiac arrest
Ensure proper grounding and correct connection. Adding a ferrite choke will help with interferance
Can you please help me rfid based petrol pump automation
Bro what's the usbserial -110 thing? The codes not being uploaded
thats the port number. you will see these kind of port number in macOS. in windows, you will see COMxx type and in linux you will see something like ttyUSB
Does it work on arduino R4 ?
Second comment
con raspberry pi asi tendras?
How print on display
Can i ask library ad8232 please???
Which application you used in program
Arduino Ide
In Which Application You Draw Your Circuit Diagram?
Fritzing
I am mechanical engineering student.What is that software you used? here to connect the wire.
probably something like fritzing
How can we see bpm
how is the bread board powered
With neggawatts
Can I know the approximate cost that i have to do this project?
600₹
Can I use arduino uno except of nano
yes you can
🥰🥰🥰🥰🥰🥰🥰
How to see bpm???
Hey i watched ur videos can you give some guidance to make this project actually I want major project quickly and submit it to college can u guide me please so i can make this
I have 100s of videos on my channel, you can browse on my channel and select your favourite, link to download codes and circuit diagram for every project is provided in video description.
I hope this helps you 😊
Please connect oled display with it
You can search for the AD8232 with a Nextion display.
There's a really cool project using the Nextion and the output is a lot more stable.
There's even some code to add filtering so this works more like a real ECG machine.
The code he's using here is very crude and doesn't produce a very stable output.
You'll notice that what should be solid straight lines are very jagged.
With this, you can not "read' the final output properly.
This is just a toy, really. But with better code, it can be better.
There may be a way to use 2 of these AD8232 devices, making it into a 4 pad sensor (not including the 2 ground pads.... including those would be 6 pads).
I haven't found a project doing that as yet, but I may decide to take a shot at it.
The problem is, the AD8232 that I bought, I've now misplaced! LOL
As for the Nextion displays, you use their editor to design the most gorgeous screens you can come up with.
If I can find my AD8232, I want to add a body temperature sensor and if I can do it, a blood pressure monitor.
With Nextion, it's easy to design a screen that will display all of those things. One could design it to look very much like the pro units in hospitals.
@@BlondieSLhey, can you tell me how a display can be placed, also the code please..?
@@funwithparijat7602 Obviously, I can't put the code here. YT doesn't like that.
As well, my code is still in dev stage.
But if you're looking to get one of the ECG boards and use a Nextion display, I'd suggest using an ESP32. For testing, you can not worry about cores, but if you get to making it serious, then you can use both cores for different code.
eg. use 1 processor to read the values from the AD8232 board and pumping through the filters.
you can use the 2nd processor to send the data to the Nextion. You'd use the Nextion's
"waveform" for the ECG draw and if you want to get fancy, you can create a little pulsing heart for the heart rate (as well as its number).
You connect the output of the sensor to the ESP32. You can find info on the best way to do that.
However, to obtain the best results, I suggest that you research 2 filters that are used in ECG machine code.
Butterworth filter
and
Chebyshev filter
If you search,
"Arduino butterworth.h" (or butterworth.ino)
and the same for Chebyshev.h or .ino
you should get the filter info which explains how to implement them.
As a guy who sucks at math and/or isn't confident in math, it took me a long time to figure this out.
ChatGPT helped me come to understand the code and from there on, I was shocked how simple it really is. LOL
On tip is, in your code that sends data, you may need to slow things down a bit.
But rather than using millis(), I suggest using micros().
Oh, I forgot, one reason for using an ESP32 instead of an Arduino, is the Tx/RX speeds are so much faster on the ESP32.
As I discovered, the latest Nextion Editor, which updates the Nextion display if its firmware is older, provides data Rx/Tx speeds up to 921600 !!! IT'S INSANE!
I did find, however, that I had to use a
*Bi-Directional Logic Level Converter*
because the Nextion's transfer rates didn't seem stable at 921600 with a direct connection of 3.3V logic.
So I used the converters to give the Nextion 5V.
Supposedly the Nextion should be happy with 3.3V, but that's not been my experience using fast speeds like that.
Part of the reason for fast speeds and separating cores for functions, is because the heart rate data should be able to react quickly, especially if sending/receiving other data while that's happening.
What I don't know how to do yet and maybe never will, is how to code to detect
A-fib and any other arrhythmia.
Again, I'm sorry that I can't post code, but honestly, even if I could, it's not something that I want to put out into the world as yet.
If I ever get this done and if I'm happy with the results, I MIGHT pop it onto GitHub.
Anyway, I hope that the info I gave you, helps you.
@@funwithparijat7602 Just as an addition and to be clear, Nextion displays are not like the usual TFT displays where you have to send draw commands to build everything on the display.
Rather, with Nextions, you use their Editor to create the most gorgeous displays your mind can create.
It's object based, so for example, for this ECG, you would place a "Waveform" object on the display where you want it. You can choose its location, size, color etc.
You can do the same with text, picture and all kinds of objects.
If you do not yet have a Nextion display, I'd suggest just downloading their Editor and start playing with it. You can do all your editing just by choosing the model of display that you intend to use for the actual project.
There are lots of youtube videos on Nextion, so again, if you are not familiar with them, watch some videos so that you get an idea how to use them.
*I HIGHLY RECOMMEND that you watch a lot of videos from "Cheap Controls" channel.
Not only does he show how to do everything with the Nextion (including waveforms) but most importantly, he shows you how to do so
*WITHOUT using the Nextion libraries* which are super bloated and overly complicated.
Those libraries are not necessary and using them introduces a complicated learning curve and your final code slows right down due to the bloat that they are.
CC shows you how to just send serial commands to do everything you want.
The memory savings is crazy!
Years ago, I was working on a project, but as I got close to 75% of memory used, using the Nextion libraries, that bug in Arduinos showed up, where they get glitchy and stop working right when that much mem is used.
So I quickly learned how he was doing it and rebuilt my project without the libraries. Just direct serial sends and receives.
My code went from the 75% with the library to about 20%-23% without the code!!!
AND everything was just much faster.
Hope that helps.
