17. LED Brightness Control Using Potentiometer

How do you plan to solve it?

•  Connect the potentiometer to A0 Pin and read the analogue voltage
• Write that analogue voltage to the PWM Pin

• /*Paste your code here*/
  // Fade an LED using PWM
  int ledPin = 9; // Pin with PWM (marked ~ on Arduino Uno)
  
  void setup() {
    pinMode(ledPin, OUTPUT);
    Serial.begin(9600);
  }
  
  void loop() 
  {
    int val = analogRead(A0);
    analogWrite(ledPin, val); // Set PWM duty cycle 
    Serial.println(val);
    delay(100);
  }
