Arduino LED Push button , potentiometer

Using Arduino Programming Questions
1

Hello,

I have on Arduino Due , one potentiometer, less, wires and resistors and I want to turn on or turn of the led by using the potentiometer. This is my code:

#define LED_PIN 11
#define POTENTIOMETER_PIN A0
void setup()
{
  pinMode(LED_PIN, OUTPUT);
}
void loop()
{
  int potentiometerValue = analogRead(POTENTIOMETER_PIN);
  
  int brightness = potentiometerValue / 4;
  analogWrite(LED_PIN, brightness);
 
}

But I want also to use serial plotter or serial monitor in order to see the value of potentiometer but I can't. I think that this will be done by command Serial.println but I have managed to do it.

Can anybody else help pe ??

I want also to do this by a push button and a led

You need a Serial.begin in setup, and a Serial.println in loop, just like in the examples.

This is not an installation or troubleshooting issue.

Please remember to use code tags when posting code.
