Final answer:
The question asks for an Arduino code to test a GSR sensor. A simple code example reads the sensor's value and prints it to the serial monitor. Calibration is essential for accurate data interpretation.
Step-by-step explanation:
The question is regarding writing an Arduino code to test a Galvanic Skin Response (GSR) sensor. Such sensors are used to measure the electrical conductance of the skin, which varies with its moisture level. Here is a simple Arduino code that you can use to read values from a GSR sensor:
int GSR=A0;
void setup(){
Serial.begin(9600);
}
void loop(){
int GSR_value=analogRead(GSR);
Serial.println(GSR_value);
delay(1000);
}
After setting up your circuit and connecting the GSR sensor to the analog pin A0 on your Arduino, this code will read the analog value from the sensor once every second and send it to the serial monitor. The Serial.begin(9600) initializes serial communication at 9600 bits per second. In the loop() function, analogRead(GSR) is used to read the sensor value, and Serial.println(GSR_value) prints this value to the serial monitor. The delay(1000) function pauses the loop for one second before reading the value again. Make sure to calibrate the sensor to get meaningful data, as raw sensor values may not be useful without proper context or scaling.
