Hello, I've just received my EMG/ECG Shield and using it with an Arduino Uno. When I read the analog values they are nearly 10 times lower than the ones I've seen on numerous videos. I get values around 50s as opposed to 500s with a simple analog read. Although the form of the signals are correct. Can anyone tell me what might be the reason?

1) Has your Arduino code manipulated the value by bit shifting, eg, sensorValue = sensorValue >> 2;
2) Did you use a resistor in your setup?
Would be helpful to see your setup and code.

What would a resistor accomplish in a setup like that btw?
