17. LED Brightness Control Using Potentiometer

How do you plan to solve it?

#define ledpin          9
#define analogReadpin   A0

void setup() {
  // put your setup code here, to run once:
  pinMode(ledpin, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  int potensiometer_input = analogRead(analogReadpin);
  int brightness = (int)((potensiometer_input * 255.0) / 1023.0);
  analogWrite(ledpin, brightness);
}
