Traffic Light Controller Using Arduino Code

Red yellow and green led.

Traffic light controller using arduino code.

Now connect the leds to the arduino as shown in the circuit diagram below. So at start green light of signal 1 and red lights at. In this project an arduino based traffic light controller system is designed. It is a simple project of light system which is used to control traffic.

Components required for arduino traffic light controller. The circuit will look like the image shown below. In previous post we built an arduino traffic light controller and in this post you are going to learn about how to make an density based traffic light controller using arduino. 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.

This is not the real time traffic light controller. Below is a short video that goes through all the steps to assembling and running the traffic lights using the arduino. 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. What you need to build an arduino traffic light controller.

1 x pushbutton switch. Red yellow and green leds. The code for this arduino traffic light controller project is simple and can be easily understood. Power up the breadboard using the arduino 5v and gnd pin.

Working of arduino traffic light controller this project is done to give you an idea of how the traffic light controller works. Although it is not the ideal implementation for real life scenarios it gives an idea of the process behind the traffic light control system. The equipment i have used in this arduino traffic light project is listed right below. Led 1 led 2 up to led 12 will be connected to pin1 pin2 up to pin12 of the arduino uno board.

3 x 100 ohm resistors color brown black brown breadboard wires. I also made an density based traffic light controller using arduino. 1 x 10k ohm resistor. In this circuit 6 led s of three different colors are used to implement traffic lights at 2 way.

Video of density based traffic light controller using arduino 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. Apart from the basic arduino you ll need. The main purpose of this project is if there will be no traffic on the other signal one shouldn t wait for that signal. Similarly the traffic light controller will work for the signal 3 signal 4 and the system will keep looping.

The components you will be required for arduino traffic light controller are as follows. Almost any arduino will work for this project providing it has enough pins. Program and working explanation. Robo india presents tutorial on the arduino traffic light controller.

Upload the code in the arduino uno and power it by using a laptop or the ac to dc adapter.
