 "Different physiological signals were important in terms of recognizing different emotions. Our results show a relationship between galvanic skin response and frustration. When a participant was frustrated, her GSR increased. The difference in GSR values of the frustrated participants was higher than the differences in both heart rate and temperature values. Similarly, heart rate was more related to anger and fear. Heart rate value of a feared participant increased, whereas it decreased when the participant was angry"<sup>(1)</sup>

 Skin conductance is considered to be a function of the sweat gland activity and the skin's pore size.Galvanic Skin Response is a measure of the skin's conductance between two electrodes. Electrodes are small metal plates that apply a safe, imperceptibly tiny voltage across the skin. <sup>(3)</sup>

+I used [[https://github.com/chris-smith/ArduinoGSR|this source]] for visualizing my GSR data.
+First;
+Open Arduino;
+Use the code from following link. And run the Arduino7

+Then Open Processing;
+You have to upload three code;

+.serial.
+You can just drag and drop to screen the files from the following link.

+Click Run; Type your serial port number "COMX"
+In that case; I have COM6
