LED Brightness Control Using PWM

Solving Approach:

How do you plan to solve it?

Code

/*Paste your code here*/
//Arduino Uno
void setup() {
  // put your setup code here, to run once:
  pinMode(9, OUTPUT);
}

void loop() {
  for (int i = 0; i <= 255; i++) {
    analogWrite(9, i);
    delay(8);
  }
  for (int i = 255; i >= 0; i--) {
    analogWrite(9, i);
    delay(4);
  }
}
