Key Features Arduino-powered, electromyography (EMG) sensor kit MyoWare board measures the filtered and rectified electrical activity of a muscle It's very simple to hook up this kit Everything you need is in the kit - battery included 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 Development Kit, an Arduino-powered, electromyography (EMG) sensor kit that provides you with a MyoWare Muscle Sensor, each MyoWare shield, and everything you need to connect them all together.The MyoWare board included in this kit acts by measuring the filtered and rectified electrical activity of a muscle; outputting 0-Vs Volts depending on the amount of activity in the selected muscle, where Vs signifies the voltage of the power source. It's very simple to hook up this kit, attach shields to the muscle sensor, stick on a few included electrodes, read the voltage out and flex some muscles!Note: The Power Shield and the LED Shield both provide power, but at slightly different voltages. Don't use both of these shields at the same time.Item Specifics1 - MyoWare Muscle Sensor1 -MyoWare Power Shield1 - MyoWare Cable Shield1 - MyoWare LED Shield1 - MyoWare Proto Shield1 - Sensor Cable --- 3 Connector10 - Biomedical Sensor Pad11 - Stackable Header --- 3 Pin, Female3 - Header --- 3 Pin, Male
