Controlling your world with the MyoWare Muscle Sensor for Arduino can make for a very interesting project. Typically, EMG feedback is reserved for very complicated and expensive systems, with the Myoware sensor you can implement it fairly easily into your prototype. 👉 Leave a tip via cryptocurrency if I've helped you out:

Straight to the point, thank you.

@diybiosensors 4 года назад

Do you know if this would work for small muscle twitches? Or is it only sensitive to intentional muscle contractions? Great video!

@MarcdeVinck 4 года назад

That is hard to say. Yes, it is sensitive, but it has to be placed in a very specific spot to work well. You can read more on the datasheet - cdn.sparkfun.com/assets/learn_tutorials/4/9/1/MyoWareDatasheet.pdf

@user-a4j6bfk78g 3 года назад

Hi, thank you for your amazing video. One question- I tried it with the basic AnalogRead sample and the output data had an average of 250 instead of 0.05 like yours. Do you know why that would be? Thank you.

@MarcdeVinck 3 года назад

If you are using the supplied code with MyoWare, then I'm really not sure. If you have your own code, my guess is the range of you mapped values if incorrect, or post processed with some more math that is making it off. I'll also add, that if the results have a range, it might not be an issue. Might want to head over to the MyoWare website and ask their tech support.

@yindigo7826 4 года назад

Hi, thank u for explanation on the safety use of muscle sensor. I want to use muscle sensor with other sensors and esp01 wifi module. I want to know if I can connect all them together on 5v pinout? Will there be complication with current drawn from arduino to sensors?

@MarcdeVinck 4 года назад

Y Indigo It depends on how many sensors, what types of sensors, and the pins you are using. In general, most sensors don’t draw a lot of current but that varies a lot.

@eritreanblackpanther7946 9 месяцев назад

Would it be dangerous to connect the arduino to a regular computer whilst having the myoware sensor on my arm?

@anthonyrickardii6198 4 года назад

Stupid question I’ve been seeing videos when they used a nano arduino, my question is it possible to use a arduino uno instead a nano for mayoware muscle sensor? Would it give the same results to?

@MarcdeVinck 4 года назад

Yes you can. They have the same pins, just a larger form factor. Voltages can be different in some cases depending on the board, but that is an easy thing to change. The sensor will give the same results.

@anthonyrickardii6198 4 года назад

Marc de Vinck thank you I really appreciate it.

@sayemsomebody6662 4 года назад

Hi! How would I be able to use the input values from the sensor to control motors? I'm trying to control multiple motors to respond to flexion of my arm muscle but I'm not sure how to connect multiple motors and a sensor to an Arduino.

@MarcdeVinck 4 года назад

To control a motor with an Arduino is best done by off-loading that process to a motor controller board. There are many out there. Check out Adafruit.com and search for motor controller. This is especially true when it comes to multiple motors, servos, or anything that uses more power than the Arduino can handle (which is low). In fact, it's always a good idea to use some kind of H-Bridge to control motors.

@fortda2323 3 года назад

Hello, is it safe to use two MyoWare sensors plugged in the Arduino Uno with USB as the power source? I want to measure the muscle activity of two or more muscles at the same time and I couldn't find anything in the internet. Hope you can help me here. Thank you!

@MarcdeVinck 3 года назад

Check out the MyoWear website for all the safety information. I don't like anything plugged into an outlet when strapped to my body.

@mynameisneb 2 года назад

What's that 3 pin connector you have on the myoware? The one with the positive, signal, and negative

@MarcdeVinck 2 года назад

One side is for adding shields, supplies power and signals, the other is also for data out. Check out the data sheet for all the info. You can find it under the "Documentation" tab on this link -- www.sparkfun.com/products/13723

@nilzie3509 Год назад

Hello Marc de Vinck, My friend and I have a school project where we want to read our EMG signals, but myoware stopped production with this sensor. Can you help us with an alternative or can we get your sensor (with pay)? thanks for making amazing content ! greets Nils

@MarcdeVinck Год назад

I didn't know that! That stinks! You are in luck. Seeed Studios has an EMG sensor and it's Grove compatible, so no soldering is required. Good luck! www.seeedstudio.com/Grove-EMG-Detector-p-1737.html

@carloskhalil6822 4 года назад

hello , can i test the duration of the contraction if it is long time or short time to detect more possible movements ???? and how it can be done ?? show me the code of it please. thank you

@MarcdeVinck 4 года назад

Sure, you can detect when the contractions occur and the time between the contractions. For the code. Sorry, I can't create the code for you, I just don't have time and I've got to pay the bills too! Try searching for measuring time with Arduino via your favorite search engine. It should be fairly easy to adapt code to work in your project.

@tahmidkawserwashee2003 4 месяца назад

i am facing noises while reading from the sensor. how you solved this problem?

@MarcdeVinck 4 месяца назад

Filter the results via code if possible. That is the easiest solution. Try averaging the results over time?

@devadingdong 4 года назад

Do you have the code for the board?

@MarcdeVinck 4 года назад

Yep! Google MyoWare! Lots of tutorials on the company website. -- www.advancertechnologies.com/p/myoware.html

@Robin_Juthberg 3 года назад

1:31 are there any alternatives to disconnecting the computer charger in order to disconnect the arduino system from the high voltage supply? For example, is there any adapter that you can place between the arduinos USB-connector and the connection to the computer, in such a manner that there isn´t any direct connection between high voltage and arduino, but att the same time, the computer is continuously charged?

@MarcdeVinck 3 года назад

I'm not exactly sure about a solution, or what you are asking specifically. Keep in mind that the MyoWare can be run right from an Arduino, without a computer. So there is no high voltage involved, and it's a lot safer. If you need external output like a serial monitor, you could use an onboard LCD, which could eliminate the required computer. I would head over to their site to get specific details, as they would be the experts. -- www.advancertechnologies.com

@Robin_Juthberg 3 года назад

@@MarcdeVinck Thank you for the quick answer! I would like to do some "long-term" (one working-day /8h) EMG testing while continuously monitoring signals from the EMG via the Arduino serial monitor/plotter. However, my laptop battery will not last that long! I have a weak recollection of seeing this safety adapter that you put between Arduino and the laptop for the purpose of fulfilling the properties described in my first message, but now I can´t seem to find it anywhere. Maybe it was just something my mind made up.

@MarcdeVinck 3 года назад

@@Robin_Juthberg Any standard USB cable will have data and power lines. Basic cables supply power only. In either case you can't isolate the computer form the Arduino if you need power. You could optically isolate the data signals with an optocoupler, but hat does not supply power. You can use an external battery pack, sized appropriately, and it can last a very long time. Just be safe!
