//The circuit:
//Pressure sensor code


// These constants won't change. They're used to give names
// to the pins used:
const int analogInPin = A0; // Analog input pin that the pressure sensor is attached to
const int analogOutPin = 9; // Analog output pin that the LED is attached to

int sensorValue = 0;        // value read from the port
int outputValue = 0;        // value output to the PWM (analog out)

void setup() {
  // put your setup code here, to run once:
  // Initialize serial communications at 9600 bps:
  Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:

  // read the analog in value:
  sensorValue = analogRead(analogInPin);
  // map it to the range of the analog out:
  outputValue = map(sensorValue, 100, 1023, 0, 367);
  // change the analog out value:
  // analogWrite(analogOutPin, outputValue);

  //print the results to the serial monitor:
  //Serial.print("sensor = ");
  //Serial.print(sensorValue);
  Serial.print("PSI ");
  Serial.println(outputValue);

  // wait 2 milliseconds before the next loop
  // for the analog-to-digital converter to settle
  //after the last reading:
  delay(2);
