Help! ENV light will not go out in myoware 2.0 muscle sensor

I’m having an awful time with Myoware 2.0 muscle sensor. I have it set up without soldering and its plugged into my (unplugged) computer. I dont have a usb isolator but as far as im aware that’s not required if the laptop isnt plugged in. no matter what i try, i cannot get the env light to go out and I cannot get the graph of its output to read anything except for 1023. i have tried different electrodes in different spots, i’ve tried different code, and I have tried different sensors entierly. I have tried everything I can thing of. I dont know whats wrong or how to fix it. Can someone please help?

Soldering the connections might help

1023 is the max value, which means it might be saturated…we generally only recommend adjusting the gain as a last resort, but it sounds like you have already done the general troubleshooting steps so it make make sense here (turn it down)

unfortunately when i tried the only thing that would happen is that the light would go out and never come back on and the graph would sorta flatline. if i turned it back up again the original problem persisted.

Make smaller adjustments…if it is maxing out at one setting and flatline/0 for another, you need to set it at the midpoint

i did. there was no inbetween.

Soldering the connections is the next step then

but i bought the parts that did not require soldering

Will you share some photos of your setup & placement? Or a link to a video

That’s looks pretty good. Maybe try it without the ref cable/shield and see it behaves any differently…I’m thinking the link shield might need to be in REF mode Getting Started with the MyoWare® 2.0 Muscle Sensor Ecosystem - SparkFun Learn
