Arduino Traffic Light Controller

Our kids love playing cars and trains so we decided to make them a cool set of traffic lights out of cardboard and arduino.

Arduino traffic light controller.

Generally they are located at junctions x roads pedestrian crossings etc. 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. 4 combinations of 4 leds will be used and placed on the breadboard. Lastly i had never worked with arduino and was looking for a project so here we are.

This traffic light controller will be used to control the flow of traffic. Here s how to build your own using an arduino and how to change the circuit for an advanced variation. Circuit diagram for arduino traffic light controller. Building an arduino traffic light controller helps you develop basic coding skills.

Traffic lights in this project we are going to make a 4 way traffic signal system using a microcontroller. Thankfully there are many relays available for usage with arduino. The resistors are used to limit the current that is going to pass through the led s. There are total of 12 leds used in this project.

Circuit diagram for arduino traffic light controller there are total of 12 led s used in this project. The arduino traffic light is a fun little project that you can build in under an hour. We included a dial to change the green light time. The code for this arduino traffic light controller project is simple and can be easily understood.

It is a simple implementation of traffic lights system but can be extended to a real time system with programmable timings pedestrian lighting etc. Each signal has 3 led s red yellow and green connected to it through the 220 ohm resistors. We think these traffic lights are pretty awesome because of a few reasons. Inland arduino uno r3 6.

If you won t use the resistors then the leds may burn due to. Arduino traffic light controller 4 way. The only way to control the ac power from arduino would be with relays. The resistors are used to limit the current that is going to pass through the leds.

If you won t use the resistors then the led s may. Like at a time there will be two red signals on any of the two. The traffic lights will give instructions to the users drivers and pedestrians by showing lights of standard color. Arduino traffic light controller for kids toys.

Traffic lights are indicating devices that are used to control the flow of traffic. In this post you are going to learn about how to make an arduino traffic light controller. These can be applied at high traffic areas to avoid traffic blocks or accidents th. In this project an arduino based traffic light controller system is designed.

And alternate the priority of who has to wait and who has to go. We didn t use the delay function as a timer. The three colors generally used in traffic. We get you started.
