Two-way Traffic Control System Using Arduino

 

Two-Way Arduino Traffic Light Controller.

The components that are required are: 

1.  6 LEDs (2 Red, 2 Yellow,2 Green)

2. Breadboard.

3. Arduino Uno

4. Jumper Wires

5.6 x 220ohm Resistors

The circuit diagram:

The Code:

// C++ code

//

int green=13;

 int yellow=12;

 int red=11;

 int green2=10;

 int yellow2=9;

 int red2=8;

 void setup() {

  pinMode(green, OUTPUT);

  pinMode(yellow , OUTPUT);

  pinMode(red , OUTPUT);

  pinMode(green2, OUTPUT);

  pinMode(yellow2 , OUTPUT);

  pinMode(red2 , OUTPUT);

  digitalWrite(green ,HIGH);

  digitalWrite(yellow ,HIGH);

  digitalWrite(red ,HIGH);

  digitalWrite(green2 ,HIGH);

  digitalWrite(yellow2 ,HIGH);

  digitalWrite(red2 ,HIGH);

  delay(1000);

  digitalWrite(green ,LOW);

  digitalWrite(yellow ,LOW);

  digitalWrite(red ,LOW);

  digitalWrite(green2 ,LOW);

  digitalWrite(yellow2 ,LOW);

  digitalWrite(red2 ,LOW);
