Today I'll be playing with a rather unique sensor, the Myoware Muscle Sensor. This unit is part of a kit that is put together by SparkFun, and it allows you to experiment with basic electromyography, or EMG technology.
This isn't an attempt to construct a medical-grade instrument, or to perform any sort of medical diagnostics. Instead, I'll show you how you can do some fun experiments with the MyoWare sensor and its shields.
We'll also see how we can SAFELY hook up the MyoWare sensor to an Arduino using a USB isolator from Adafruit. This eliminates the possibility of any contact with ADC ground through the attached computer. I'll also show you other SAFE, battery-powered ways to use the MyoWare sensor with a microcontroller, without the isolator.
And I'll make a (FAILED) attempt to control a MeArm robotic arm using two MyoWare sensors. While I do manage to get some control over the claw, I had a difficult time controlling the arm. But the code allows for a lot of fine-tuning, so I may one day actually succeed!
Here is the Table of Contents for today's video:

40:58 - Conclusion
42:43 - Ouch!
Aside from (poorly) controlling a robot arm, these sensors have applications in gesture sensing and devices to assist with mobility. Hopefully, the video and its associated article will give you a few ideas for using the MyoWare Muscle Sensor.

Hi everyone - It's come to my attention that there has been someone masquerading as myself, responding to some comments here with a link to a Telegram chat to win a prize from me. THIS IS A SCAM, I am not holding a contest, nor do I have a Telegram account. PLEASE DO NOT RESPOND TO THESE MESSAGES!!
It's happening on a lot of my videos, I'm taking steps to remove them manually, but as I have 162 videos, it will take some time. If you do run across a suspicious comment, I would appreciate you letting me know at info@dronebotworkshop.com.
Thanks!
Bill (The real one!)
Hi Bill, another brilliant video- Thanks, I have a money saving *(and eco friendly) tip for the pads. I use them for my T.E.N.S machine, and after using the pads, a simple rinse under a cold water for a few seconds, shake dry (don't be tempted to use tissue) and re adhere them to the original backing plastic- I can get upto 10x use from one set of pads, saving me literrally $$$$ pae annum, asd they are really expensive here in the UK.
It’s crazy how this video hits my feed the day before I have an actual EMG appointment. Love your content ❤️. I’ll stay tuned for more of your content!
The second I saw you put on the sensors, I was already thinking "they have to come off at some point, that will be a pain". In the end, my conclusion was right. Thank you for sharing this, it is an interesting concept.
Thank you for pointing this out! As always, a superb video!
I absolutely love this channel and its projects. Please do more medical engineering-related videos and maybe start venturing into Brain-Computer Interfaces.
I love the detailed explanation of everything you gave sir ,,,
Very appreciated
we have a good laugh at the end when you remove the adhesive patches. in short, your video is very interesting and fun. thank you very much.
Best channel, from Brazil. Love it.
This video was what i was waiting for a long time well explained tones of thankings
Really nice video. I liked your trick to stabilize the y axis. If I may, I would suggest to smooth out the sensor output. My go to method is linear interpolation:
float lerp(float newValue, float oldValue, float delay)
{
return newValue + delay * (oldValue - newValue);
}
Or you can simply calculate average from last two values. That way your input for the robot arm will be less shaky.
Bill appreciate the video gonna have to get one and play with it soon
Ouch! On removing those pads! Super demo.
The most amazing video of yours. Thank you so much!
Good content as always
Smart idea using the 3M pads. That is a fraction of the price as the ones from SparkFun. There is also the BioProtech ones on Amazon for even cheaper. I really like the little robot arm too! I looked them up and found it is an Opensource project with the files for laser cutting them available for free. Had it downloaded and cutting before I hit the end of the video! Already planning a build with my son for the ESP32 car you did a few months ago with some modifications. This will make another fun project, although the MyoWare are sold out at the moment.
Great video!
Thanks for good video tutorial.
I didn't see this vid in subscription section and got notification now, im from South Asia
Excellent video! I think I would shave my arm in those spots if I try
Very good
uffffffff, me salvaste con este video, saludos desde Colombia
Really interesting
Placing the upper sensor over the triceps would give you extension of the me amr.
Hello Bill, I really enjoy your videos. Do you plan to continue DB1? I watched all the videos but notice 15 is the last one. Keep up the good work!
Good job
Execent video thank you very much
At 19:35, stick the pads on 1st to yours, then plug the cables in. Much easier.
Or attach the cables while they are still on the backing. Much easier.
Güzel video. Teşekürler
terimakasih pak ap atas pembelajarannnya
🥶kak
Great content, could I ask for a video showing how to use the MCP23017 with the Arduino?
You don't need to connect the servos to pwm pins, a while ago the standard servo library started using 1 timer for the Arduino that can control several servos on any pin. The only disadvantage is that you can't use the PWM pins that depend on that timer as PWM of course.
Ow:interjection Used especially in response to sudden pain. Looks like the 3M pads stick the best! Are they the same as the pads they use for EKG? Great info, always amazed at what you come up with.
Beatifull👍👍
Magnificent
have you built or reviewed the Arduino IoT Air Quality checker based on the Arduino MKR Wifi 1010 or have any good references there of? thanks in advance!
Güzel video
Hi bill Video about what is
Pixhawk how does it work
Thanks
Hi Bill,
Thanks a lot for this video I really appreciate that.
So, I have just one question about it. Are we able to use this kind of system to improve some exercise at the gym?
For example, we can create an app in order to integrate those systems and provide to the work out specialist important information, like posture, charge etc.
It's nice
Nice
is there a board combination of EMG and motor drive?
Bu adam bu işleri biliyor
The time has come for the Minority Report interface.
Süper video
Super
Very Nice Çok Íyi :)
Hello DroneBot Workshop, 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
Guys, I am having problems with my sensor and I would like to know if anyone can help me.
When I turn on the sensor, it already starts with a 900 value on the Y Axis, without making any move...
I am turning directly on the USB power of my laptop, is there any problem? Or I just lost my sensor?
Tks
nice
Somewhere around 24 min it looks like you may be holding your forearm off the table; if so it would seem that would make readings scattered. I looked more and saw your arm off the table
Good🙏
Sir make a review about stm32(bluepill)and blackpill
With some basic sketches
Nice outro :)
Very unique workshop. More funny outtakes in the future? ...so long as it doesn't involve hair removal.
Very ambitious, but the best of luck to you, my old friend.
If it is a muscle sensor, if each "o" to vibrate after pasting at parts of body, like a massage?
Another if a sensor for in front of Shoes like if have a Lump then to prevent Fall, a self-reminder by vibration at leg? Cool safety idea right? Especially during a fight or war we need to be safer.
the emg sensors dont detect the hand moving up and down very well but if you try flexing your bicep you might get the desired results
Hey have u tried this sensor..plz let me know the response of this myoware sensor as i want to sense the muscle movements or the biceps movement
If I had muscles I would totally build this
Please make video on db robot
This channels is amazing but i would love to see this projects in pic because in my college arduino is forbidden
And much less painful than getting an EMG done at the MD. Not any needles needed.
👏👏👏
Süper
👏👏👏👏
Hi sir
THE CLAWWWWWWW
Wow. I really respect people like you for whom the limits don't exist even within a little workshop. You help us understand how to achieve anything without being Elon Musk. Thanks. Have a great Christmas.
güzel
You can make a dog robot by Servo motor
✌
Hello
İyi
I'm a doctor now .😁😁👍can I wear my stethoscope and white lab coat to black tie parties. I'll say it's all cool bill showed us how lol cool video😁👍🤖
Do you by any chance sell any consultation services? I am a beginner, and I would REALLY pay to get my stepper motor to work lol. I've watched a lot of tutorials, and thought I've understood how to construct the circuit and code, yet I cannot get it to work. I'm working on a robot that I'm planning to patent, so it would be awesome if we could talk.
How is it going
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Gerçek işçilik
