Have your next project be controlled by your muscles with this pack of Muscle Sensor Surface EMG Electrodes! Pair the electrodes with the MyoWare Muscle Sensor and a microcontroller (ie. Arduino, or anything else with analog input reading ability) to create a DIY low-cost version of an EMG or an electromyograph!

We chosse a very high resistance resistor R1, because most of the light through the finger is absorbed,it is desirable phototransistor sensitive enough.Resistance can be selected by experiment to get the best results.
