Pressure Sensor Data Collection

Arduino
This code records the analog values for pressure that were detected by the four sensors and converts the values to voltage readings.
// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
  // read the input on analog pins 0-3:
  //this initiates the analog pin 0 to receive data from the pressure sensor at      the heel
  int heelValue = analogRead(A0);
  //this initiates the analog pin 1 to receive data from the pressure sensor at      the ball of the foot
  int ballValue = analogRead(A1);
  //this initiates the analog pin 2 to receive data from the pressure sensor at      the big toe
  int bigtoeValue = analogRead(A2);
  //this initiates the analog pin 3 to receive data from the pressure sensor at      the outermost toe
  int littletoeValue = analogRead(A3);
  // Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V):
  float heelvoltage = heelValue * (5 / 1023.0);
  float ballvoltage = ballValue * (5 / 1023.0);
  float bigtoevoltage = bigtoeValue * (5 / 1023.0);
  float littletoevoltage = littletoeValue * (5 / 1023.0);
  // print out the value you read, this format allows the values to entered into separate columns in an Excel sheet
  // if the Data Streamer function is used:
  Serial.print(heelvoltage);
  Serial.print(",");
  Serial.print(ballvoltage);
  Serial.print(",");
  Serial.print(bigtoevoltage);
  Serial.print(",");
  Serial.print(littletoevoltage);
  Serial.print(",");
  Serial.println();
  delay(100);
}
