4. Modify the variable threshold to the recorded maximum value. Recommend to modify it to the maximum +100 to improve anti-interference. Reload the sample code to
the Arduino control board.
5. Open the serial monitor of Arduino IDE, make a fist and loose it for once then you can see the printed value. Making a fist gently will not count and making a fist with
more power will not increase the count value. Only a strong fist and loose can make sense. In this way, we realize the precise counts.
If you found the count accumulated when loose the fist, it would be caused by low threshold value. You can add extra 100 on the variable threshold , then reloading the
sample code to the Arduino control board and check the result. You can repeat this step until the result is satisfied.

This sensor can count the muscle activities precisely after calibration on putting the sensor to a position. It can be applied to push-up counts, dumbbell curl counts. It also can
be applied to human-computer interaction, such as play Flappy Bird with EMG signal made by fist.
Besides the basic function, the analog EMG sensor can also detect muscle activity strength by signal intensity. You can refers to the More Documents in the end page of Wiki.
FAQ
Q1. Where should I put the dry electrode? Is there any special requirement?
A. In general, the corresponding 3 metal dry electrode plate needs not pay attention to the reference voltage. It only need to consistent with the direction of muscle. You
can refer to the image as below of the placement.
