For your convenience, the following troubleshooting tips for the MyoWare 2.0 Muscle Sensor are provided from the MyoWare 2.0 Quick Start Guide.

  • The Vin LED should remain on constantly as long as the sensor is powered.
  • The ENV LED might immediately turn on when power is turned on but it should turn off after a second or two; afterwards, it should only turn on when the sensor detects muscle flexion.
  • The ENV LED might sporadically turn on and off or simply remain on if the sensor (or external cables) is not connected to electrodes on the skin. This is normal behavior.
  • The ENV LED lighting up seemingly at random while connected to electrodes on the skin usually indicates poor contact between the electrodes and the skin. Try cleaning the area and applying new electrodes.
  • The ENV LED not lighting up during flexion could be caused by various issues with the sensor setup. Double check the steps and tips of this guide to ensure proper setup.
  • Most of the time the sensor gain does not need to be adjusted at all.
  • Recommended that you do not adjust the sensor’s gain until you get a consistent, quality signal from the sensor.

  • Is the blue LED flickering or not fully lit when the MyoWare 2.0 Wireless Shield is connected to a central device? Try checking your LiPo Battery and ensure that it is charged.
