Measuring muscle activation via electric potential, referred to as electromyography (EMG) , has traditionally been used for medical research and diagnosis of neuromuscular disorders. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG sensors have found their way into prosthetics, robotics and other contol systems. Yet, EMG systems remain expensive and mostly outside the grasp of modern hobbyist.
This instructable will teach you how to make your own muscle sensor to be incorporated in your next project. Use it to control video games, robot arms, etc all with your muscles!
