Using our muscles to control things is the way that most of us are accustomed to doing it. We push buttons, pull levers, move joysticks... but what if we could take the buttons, levers and joysticks out of the equation? This is the MyoWare Muscle Sensor, an Arduino-powered, all-in-one electromyography (EMG) sensor from Advancer Technologies. The MyoWare board acts by measuring the filtered and rectified electrical activity of a muscle; outputting 0-Vs Volts depending the amount of activity in the selected muscle, where Vs signifies the voltage of the power source. It's that easy: stick on a few electrodes (not included), read the voltage out and flex some muscles!
The MyoWare Muscle Sensor is the latest revision of the Muscle Sensor of old, now with a new wearable design that allows you to attach biomedical sensor pads directly to the board itself getting rid of those pesky cables. This new board also includes a slew of other new features including, single-supply voltage of +3.1V to +5V, RAW EMG output, polarity protected power pins, indicator LEDs, and (finally) an On/Off switch. Additionally, we have developed a few shields (Cable, Power, and Proto) that can attach to the Myoware Muscle Sensor to help increase its versatility and functionality!
Measuring muscle activity by detecting its electric potential, referred to as electromyography (EMG), has traditionally been used for medical research. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into all kinds of control systems.
Note: Biomedical sensor pads can be found in the Recommended Products section below to be purchased separately.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Bought the myoware sensor for my class project and it works perfectly
It is just the device that we need for our Project.
We purchased 6 for a lab class I'm teaching. Only 4 worked well. Other two were totally unreliable.
Sorry to hear about the issues with the sensors. Have you reached out to our technical support staff? They can help to troubleshoot your setup and get you replacement sensors for the class. You can reach them at firstname.lastname@example.org
The sensor works almost fine but the attached wire for the reference terminal is not too long enough so we are unable to get the required values accurately. Moreover, there is not provided any manual for specifically this model. We will be thankful to you if you people help us on its REAL TIME DATA acquisition.
Have you contacted our technical support department over at Techsupport@sparkfun.com ? They can help you to troubleshoot and potentially help you out with your real time data acquisition if you reach out to them.
