Traffic Light Controller Using Arduino

Below is a short video that goes through all the steps to assembling and running the traffic lights using the arduino.

Traffic light controller using arduino.

Each signal has 3 leds red yellow and green connected to it through the 220 ohm resistors. We get you started. It is a simple project of light system which is used to control traffic. Red yellow and green led.

Consider the following gif image showing a loop of traffic light operations. The equipment i have used in this arduino traffic light project is listed right below. Thankfully there are many relays available for usage with arduino. Robo india presents tutorial on the arduino traffic light controller.

In this circuit 6 led s of three different colors are used to implement traffic lights at 2 way. The code for this arduino traffic light controller project is simple and can be easily understood. There are total of 12 leds used in this project. How to make arduino based traffic light controller.

The resistors are used to limit the current that is going to pass through the leds. Video of density based traffic light controller using arduino. If you won t use the resistors then the leds may burn due to. Like at a time there will be two red signals on any of the two.

It is a combination of three colors of light that are red yellow and green. Building an arduino traffic light controller helps you develop basic coding skills. The only way to control the ac power from arduino would be with relays. The traffic light works on 110v ac power a micro controller on 5v 12v dc.

Here s how to build your own using an arduino and how to change the circuit for an advanced variation. Traffic lights are signaling devices that are used to control the flow of traffic on the intersections of a road pedestrian crossings and other locations. Here we have demonstrated traffic lights for the 3 ways road and the code glows led s on all the three sides in a particular sequence in which the actual traffic lights works. By hamza iqbal october 15 2019.

The aim of the project is to implement a simple traffic light controller using arduino uno where the traffic is controlled in a pre defined timing system. The arduino traffic light is a fun little project that you can build in under an hour. The project is also implemented in the same manner. Future work we will update this system with when a vehicle try to move even during red signal it will turn on an alarm to warn the driver of the vehicle and will send the alert to the traffic warden with the picture.
