circuit connection

connect the leds sequentially from 4 to 13

Code

code of the project

Arduino
you can write the code or paste it
i will personally recommend you to write it
byte ledPin[]={4,5,6,7,8,9,10,11,12,13};//to define the led's pin
int ledDelay(65);
int direction =1;
int currentLed;
unsigned long changeTime;//this is taken as unsigned because of the function in which it will be used in future
void setup() {
 for (int x=0;x<10;x++)
 {
   pinMode(ledPin[x],OUTPUT);
 }
 changeTime=millis();
}
void changeLed()
{
 for( int x=0;x<10;x++)
 {
   digitalWrite(ledPin[x],LOW);
 }
 digitalWrite(ledPin[currentLed],HIGH);
 currentLed+=direction;
 if (currentLed==9)
 {
   direction=-1;
 }
 if (currentLed==0)
 {
   direction =1;
 }
}
void loop() {
 // put your main code here, to run repeatedly:
if ((millis()-changeTime)>ledDelay)
{
 changeLed();
 changeTime=millis();
}
}
