Arduino Muscle Sensor (EMG) Tutorial

In this video you can see how you can implement a muscle sensor to your own arduino projects.

Could you share how you set up the arduino board and wiring? Looks very interesting.

What is the equipment you connect sensor at 3:26? Is this an EMG equipment you use to check values?

[juschu]

In this case it won't cause any actual problems (in other applications that could be different) but it's bad practice to write something like

if (analogRead(5) > 60) {
...
} else if (analogRead(5) < 60) {
...
}

You're ignoring the case where analogRead(5) == 60 is true.
You should rather just execute the else block without any condition. If you do it you should use the <= operator instead of just the < operator.
But you don't need a condition at all because when analogRead(5) > 60 is false (which will cause a jump to else) then it's guaranteed that analogRead(5) <= 60 is true.

If you want to do it absolutely perfectly you would call analogRead() once, save its return value it to a variable and then check that variable in the condition. Calling the function twice means you sample the voltage on the ADC twice, which means you could get two different values where you would expect two identical values. Of course that would also not happen if you don't use the codition for the else block.

My results are not showing differences between open and closed hand... unfortunatelly. I tried put sensors in various muscle groups.

[bigoteees]

can you please give us the connections of the circuit etc? thanks

[mohammadhaboush]

thank so much,
I would like to ask you a question,
I have a project in my college,
I need to move each finger of the hand alone,
how can I do that??

Hocam ben bu aksana nerede görsem tanırım :) Bu videoyla ilgili bir sorum olacaktı

[anushka.narsima]

I'm trying to make a wearable device to track gym exercises. But the issue is to track leg exercises like leg presses, while wearing only a watch. Does this sensor react to that? I mean the whole body tenses up while using big gym equipment, even if it's mainly the legs

Thank you for your nice and clean expression.But i need to move all the fingers seperately with emg sensor, i think it is possible.Should I use multiple sensor for different muscles.Can you help me about this kind of project?Is there any information or source or video about this kind of project that you know?

[hristijanivanoski]

Lovely !
Where i can find screws for fingers or similiar solution?
Thanks

hola!ns porq pero en el serial monitor me va súper rápido, es decir las subidas y bajas van muy rápido, y no me detecta al cerrar el puño y al abrirlo, pero sí q al ir tocando un poco el sensor emg varían los numeros, q puede ser?

[Datrandomasianguy]

did you use any filter? because the output of my sensor is pretty noisy and i have to use digital filter to reduce the noise.

[misaelmorales]

donde podria conseguir informacion de como hacer una proteccion al paciente con un circuito

[linasaeed]

I use the same sensor but the output of signal is a random... What is the solution of this problem

[arifatululliya]

Hi sir i have followed all your steps and used your code too but the servos do not move smoothly, can you help me how to make it smooth?

[NHabibK]

Hi sir ..
I want to ask
why my project generates noise waves in Serial Monitor?
and not responding to my muscles, nothing has changed from the noise wave.
I am using Arduino Uno V3 and EMG Shield from Olimex.

[MaxLohMusic]

Does it need to be 3 electrodes per muscle or can it be 2 per muscle and only 1 neutral is needed for all of them? Is there a way to get multiple muscles per sensor? Or do you need 1 sensor per muscle?

[shraddhashinde]

Hi . I have a doubt . Is this a haptics master and slave kind of control?

[MaxLohMusic]

Is it possible to do two legs, two arms, and core muscles, all at the same time?

[meftahmedhedi]

how can i find EMG SENSOR in proteus or tinkercad ?
