    IxLab 2020S -  NYU Shanghai
    recorded during class 18 - Programming Arduino
    Ideas for exercises to practice:
    get creative with the application of the map function 
    change the pin number of the components
    add a second potentiometer

    Based on AnalogReadSerial - http://www.arduino.cc/en/Tutorial/AnalogReadSerial
    This example code is in the public domain.

const int led = 11;
const int pot = A0;
// the setup routine runs once when you press reset:
void setup() {
  Serial.begin(9600);
  pinMode(led, OUTPUT);
  pinMode(pot, INPUT);
}

// the loop routine runs over and over again forever:
void loop() {
  int sensorValue = analogRead(pot);   // read the 10 bits from the analog digital conversion module
  int ledValue = int(map(sensorValue, 0, 1023, 0, 255)); // the maximum I received is 1023 (10 bits)
  analogWrite(led, ledValue); //it writes on the PWM module, so it can accept only 8 bits
  Serial.print(sensorValue);
  Serial.print(" was mapped to the LED with "); //adds text in between
  Serial.println(ledValue); // print out the value you write
  delay(1);        // delay in between reads for stability
