Arduino won't detect V3 Muscle Sensor

Other Hardware Sensors

Hello, I'm new to programming with Arduino and I'm having some problems with V3 muscle sensor.

I followed this tutorial How to control servo motor with EMG Muscle Sensor - YouTube to make the circuit and program it, and initially I didn't have any problem: it worked.

But now Arduino is not detecting any signal, when I open the Serial Monitor to see the value It's taking, It's always 0.

I don't know where to start to solve this problem. I think maybe the electrodes aren't working properly? Because the port where the muscle sensor is connected is the one I use in the code so I guess the Arduino One is working properly.

Thanks!

Hi - Unfortunately your Muscle Sensor V3 is very likely a Chinese counterfeit of our sensor and likely hasn't gone through all the testing and quality controls that are part of our process. We stopped manufacturing the authentic Muscle Sensor V3 in 2015 when we released the MyoWare.
