Knight Rider W/ Arduino

Hello guys , this is my first project . Maybe smth is wrong .

Step 1: Items What You Need ...

7x Red LED's

7x 330 Ohm Resistor

A lot of wires

1x Push Button

Arduino ( i am using nano )

Breadboard

Step 2: Schematic

Look picture for more details....

Step 3: Code

Code works , i made my own code , maybe smth is wrong , but how i said , this is my first project .

sides are LED's 1 and 7;

almostsides are LED's 2 and 6;

middle are LED's 3 and 5;

center is LED 4; //pins

If you wanna add some circuits:

1 Step : Create new case .

2 Step : When you complete case type break;

3 Step : randNumber = random(1, 5); change the second number , like if you have 6 cases you need to change second number above , like : 5 cases , type 6 ....

Thanks , for reading .

Hope you enjoyed . ;)
