Hello,
I had a problem when testing the MyoWare muscle sensor 2.0. The ENV LED did not light up when I used my arm to exert force. I also tried wiring the sensor to the Arduino Uno development board, but the ENV value did not change. It just outputs a bunch of random numbers.
I have tried using the LED Shield to connect to the muscle sensor, and it lights up. Are there any other solutions? Thank you.
