**Test Sketches**

Blinking:

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);
  delay(250);

  digitalWrite(LED_BUILTIN, LOW);
  delay(250);
}

Reading from Potentiometer:

void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
}

void loop() {
  // Read the potentiometer on analog input #0
  int sensorValue = analogRead(A0);
  // print the value
  Serial.println(sensorValue);
  // wait
  delay(1000);
}

Use Potentiometer to dim LED:

const int LED_PIN = 11;

void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);

  pinMode(LED_PIN, OUTPUT);
}

void loop() {
  // Read the potentiometer on analog input #0
  int sensorValue = analogRead(A0);

  // Use the sensor input to manipulate the delay
  int iDelay = sensorValue / 1000.0f * 5;
  digitalWrite(LED_PIN, HIGH);
  delay(iDelay);
  digitalWrite(LED_PIN, LOW);
  delay(1);
}
