example output with the sensors connected on the forearms and right leg. Your serial output should spike between +300/-200 around the center value of about
~500.
The serial data is hard to visualize if you are just viewing the values. If you are using Arduino IDE v1.6.6+, there is an option to view the data on a graph using
the Arduino Serial Plotter as one option. In the Arduino IDE, select Tools > Serial Plotter. You should see a waveform similar to the image below when the
sensors are placed correctly and not moving.
