Introduction: Arduino Drag Race Light Tree

I'm new to Arduino so I was excited to try this out.  I also Drag race 1/24 scale slotcars.  I built a homemade 24' drag strip to practice. I need the tree to be the same as the race track  so my reaction time might  improve.  I'm not sure if I have the timing right, but it's getting close. See the video below.



The Arduino = Arduino UNO purchased at Radio Shack

The Breadboard=  Radio Shack (not necessary, but I already made the prototyping stand.  https://www.instructables.com/id/Acrylic-Arduino-Prototyping-Stand/)

LEDs and jumper wires = you guessed it... Radio Shack

The power source is Altoids charger that supply's 5v to the Arduino board  ( https://www.instructables.com/id/Another-Altoids-Ipod-Charger/)
You can also use a 9v battery with  resistors that are appropriate or use usb from laptop or desk top computer.  

The software I used I downloaded from  http://arduino.cc/en/Main/Software

I understand there are many ways one can do this. I chose to build it this way because this is what I had.  

I connected the jumper wires to the #2,4,6,8,10 pins found on the Arduino board and the long leg of the Led are placed in line with the end of the red jumper wires on the breadboard.
.
The ground pin is located above the #13 pin  (GND) on the Arduino board. 


The Code I wrote is a modified version of the blink example: 

/*
  Blink
  Turns on an LED on for 1 second, then off for 1 second.
 
  This example code is in the public domain.
*/



void setup() {
 
  // initialize the digital pin as an output.
  // Pin 13 has an LED connected on most Arduino boards:
  pinMode(2, OUTPUT);
  pinMode(4, OUTPUT);
  pinMode(6, OUTPUT);
  pinMode(8, OUTPUT);
  pinMode(10, OUTPUT);
}

void loop() {
  digitalWrite(2, HIGH);  // White Led on for 1 second
  delay(1000);            
  digitalWrite(2, LOW);   // LED turns off for 1/2 second  
  delay(500);             
  digitalWrite(4, HIGH);  // Yellow led on 1/2 second   
  delay(500); 
  digitalWrite(4, LOW);   // LED turns off for 1/2 second
  delay(500);  
  digitalWrite(6, HIGH);  // Yellow Led on for 1/2 second
  delay(500);            
  digitalWrite(6, LOW);   // LED turns off for 1/2 second
  delay(500);             
  digitalWrite(8, HIGH);  // Yellow Led on for 1/2 sec 
  delay(500); 
  digitalWrite(8, LOW);   // LED turns off for 1/2 second
  delay(500);
  digitalWrite(10, HIGH);   // Green Led on for 2 seconds
  delay(2000);            
  digitalWrite(10, LOW);   // Green LED turns off for 3 seconds
    delay(3000);
}






As soon as I learn how to move it to it's own board and add a start switch I will put it in a box and mount it permanently.
