My Myoware 2.0 works fine when is it powered by the battery pack and not connected to anything else. It is not working when it is connected to the Arduino Uno Board. I want to visualise the data using a serial plotter, but as soon as I connect the sensor to the board with the ground, the env LED lights up and stays on and there is no muscle activity detection. This also happens when the sensor is powered by the arduino uno Board with 3.3V or even 5V. Please help. I have connected a USB Isolater but the problem persists even if I take the laptop off charging. I had bought myself two sensors but both of them are giving me the same problem. It cannot be the placement of the sensor because when it is connected with just the battery pack, it works just fine.
