Arduino Multi Traffic Light Controller Project

The Arduino Traffic Light Controller Project is an exciting endeavor that combines electronics, microcontroller programming, and real-world applications. It replicates the functionality of a traffic light system, offering a hands-on experience for Arduino enthusiasts and engineering students. This project showcases how Arduino can be used to simulate and control a traffic intersection.

Component List:

LEDs and Resistors: Connect the red, yellow, and green LEDs to digital pins on the Arduino through their respective resistors. These resistors limit the current and protect the LEDs.

In the Arduino IDE, create a sketch to control the LEDs, simulating a traffic light’s behavior. You can program the LEDs to switch in a sequence, mimicking the actual traffic light pattern.

Arduino code:

void setup() {
// configure the output pins
pinMode(2,OUTPUT);
pinMode(3,OUTPUT);
pinMode(4,OUTPUT);
pinMode(5,OUTPUT);
pinMode(6,OUTPUT);
pinMode(7,OUTPUT);
pinMode(8,OUTPUT);
pinMode(9,OUTPUT);
pinMode(10,OUTPUT);
}
