This project is made using 8 LED. You can use more or less than 8 LEDs and can change the code accordingly. Resistance with LEDs are used to limit the current and potentiometer is used to control the switching frequency of LEDs.

Arduino Code:

int led1 = 2;
int led2 = 3;
int led3 = 4;
int led4 = 5;
int led5 = 6;
int led6 = 7;
int led7 = 8;
int led8 = 9;
int pot = A0;
int delayperiod = 0;
int val;

void setup()
{
pinMode( led1, OUTPUT);
pinMode( led2, OUTPUT);
pinMode( led3, OUTPUT);
pinMode( led4, OUTPUT);
pinMode( led5, OUTPUT);
pinMode( led6, OUTPUT);
pinMode( led7, OUTPUT);
pinMode( led8, OUTPUT);
pinMode( pot, INPUT);
}

void loop()
{
val = analogRead(pot);
delayperiod = map(val,0,1023,0,1000);

digitalWrite(led1, HIGH);
delay(delayperiod);

digitalWrite(led2, HIGH);
delay(delayperiod);

digitalWrite(led3, HIGH);
delay(delayperiod);

digitalWrite(led4, HIGH);
delay(delayperiod);

digitalWrite(led5, HIGH);
delay(delayperiod);

digitalWrite(led6, HIGH);
delay(delayperiod);

digitalWrite(led7, HIGH);
delay(delayperiod);

digitalWrite(led8, HIGH);
delay(delayperiod);

digitalWrite(led1, LOW);
delay(delayperiod);

digitalWrite(led2, LOW);
delay(delayperiod);

digitalWrite(led3, LOW);
delay(delayperiod);

digitalWrite(led4, LOW);
delay(delayperiod);

digitalWrite(led5, LOW);
