width) {
for(ArrayList sensor : sensors) {
sensor.remove(0);
}
}
}
println(“data [0]”, " = ", data[0]);
//println(“data [1]”, " = ", data[1]);
// println(“data [6]”, " = ", data[6]);
//println(“data [7]”, " = ", data[7]);
}
Here, int [] data is the signal data I am receiving every millisecond from 8 EMG sensors. How do I retrieve the values from it ? Sorry to bother you, I am not really proficient in processing. 😛

Hi,
I tried using the signal filter library but for some reason, it’s just crashing my sketch. Do you know of any other library that would help me do the job? Also, I am using this Myo : [https://www.youtube.com/watch?v=1u5-G6DPtkk](https://www.youtube.com/watch?v=1u5-G6DPtkk)

### _Please format your code_ 😊
It consist on these two steps:
1. In your code editor (PDE, VS code, Eclipse, etc) ensure you execute the beautifier function. This function automatically indents your code. Auto-indenting makes your code easier to read and helps catching bugs due to mismatch parenthesis, for instance. In the PDE, you use the key combination: `ctrl+t`
2. You copy and paste your code in the forum. Then you select the code and you hit the formatting button aka. the button with this symbol: ``
That’s it! Please notice you do not create a new post in case you need to format something you already posted. You can edit your post, copy the code to the PDE, indent the code properly there and then past it back here, format the code and \>\> **save** \<\< the edits.
## Extra info:
Formatting your code makes everybody’s life easier, your code looks much better plus it ensures your code integrity is not affected by the forum’s formatting (Do you know the forum processes markup code?) Please visit the sticky posts or the FAQ section/post to learn about this, other advantages and super powers you can get in this brand new forum.

You can implement a moving average as it is one of the simple ones.

Do you mind showing your attempt?

Not really to answer your question but related to the topic:
Does anybody know how that band works?
Does it pick up electric signals of the nerves and if so what voltage levels can be expected here and how does it pick those up? Wires?
Or is it a capacitive sensor? Or pressure? Or acceleration and gyro?

@kfrajer wow that’s an interesing read. Thank you!
