LEDs Fading Speed Control

Solving Approach:

How do you plan to solve it?

Code

/*Paste your code here*/
#define LED_1 3
#define LED_2 5 
#define LED_3 6
#define LED_4 9
#define LED_5 10

#define POT_PIN A0

uint8_t pin_arr[5] = {LED_1, LED_2, LED_3, LED_4, LED_5};
uint8_t value_arr[5];
int pot_value=0;
int mapped_value = 0;
int wait = 0;

void fadeControl(void)
{
  for(int v=0; v<256; v++)
  {

    analogWrite(pin_arr[0],255-v);

    analogWrite(pin_arr[1],v);

    analogWrite(pin_arr[2],255-v);

    analogWrite(pin_arr[3],v);

    analogWrite(pin_arr[4],255-v);

    pot_value = analogRead(POT_PIN);

    wait = map(pot_value,0,1023,0,10);

    delay(wait);

  }


  for(int v=255; v>=0; v--)
  {

    analogWrite(pin_arr[0],v);

    analogWrite(pin_arr[1],255-v);

    analogWrite(pin_arr[2],v);

    analogWrite(pin_arr[3],255-v);

    analogWrite(pin_arr[4],v);

    pot_value = analogRead(POT_PIN);

    wait = map(pot_value,0,1023,0,10);

    delay(wait);

  }
}


void setup() {
  // put your setup code here, to run once:
  for(int i=0;i<5;i++)
  {
    pinMode(pin_arr[i],OUTPUT);
  }

}

void loop() {
  // put your main code here, to run repeatedly:

  
  fadeControl();


}
