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 ---

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](https://learn.sparkfun.com/tutorials/getting-started-with-the-myoware-20-muscle-sensor-ecosystem/-myoware-20-link-shield) ---

It might be a defective unit, then - Was it purchased from us? If so head over to [Return Policy - SparkFun Electronics](http://www.sparkfun.com/returns) (contact vendor if purchased elsewhere) and we’ll get ya squared away ---

but i tried a minimum of three seperate sensors, is it reasonable theyre all defective? ---

It is rather unlikely that all 3 are defective…but the thing with the myoware items is there are like 13 variables that can all individually throw off the measurements. I re-iterate the fact that you got saturation and then nothing by adjusting the gain indicates that it is mis-adjusted, but I can’t offer much besides telling you to go through ALL of the guides (3) thoroughly and triple-check every single thing > **[MyoWare\_v2\_QuickStartGuide.pdf](https://cdn.sparkfun.com/assets/learn_tutorials/1/9/5/6/MyoWare_v2_QuickStartGuide.pdf)** > > 4.37 MB > **[MyoWare\_v2\_AdvancedGuide-Updated.pdf](https://cdn.sparkfun.com/assets/learn_tutorials/1/9/5/6/MyoWare_v2_AdvancedGuide-Updated.pdf)** > > 8.97 MB [https://learn.sparkfun.com/tutorials/1956](https://learn.sparkfun.com/tutorials/1956) ---

unfortunately i already did all that, as well as passed them off to an electrical engineer of over twenty years experience who unfortunately had the same issues as i did. ---
