This traffic light controller will be used to control the flow of traffic.
Arduino traffic light controller code.
The equipment i have used in this arduino traffic light project is listed right below.
Our kids love playing cars and trains so we decided to make them a cool set of traffic lights out of cardboard and arduino.
We think these traffic lights are pretty awesome because of a few reasons.
1 x 10k ohm resistor.
In this circuit 6 led s of three different colors are used to implement traffic lights at 2 way.
1 x pushbutton switch.
Almost any arduino will work for this project providing it has enough pins.
3 x 100 ohm resistors color brown black brown breadboard wires.
Apart from the basic arduino you ll need.

Robo india presents tutorial on the arduino traffic light controller.
Arduino traffic light controller 4 way.
Red yellow and green leds.
What you need to build an arduino traffic light controller.
It is a simple project of light system which is used to control traffic.
In this project an arduino based traffic light controller system is designed.
The circuit will look like the image shown below.
In this project an arduino based traffic light controller system is designed.
Red leds 4 pieces yellow leds 4 pieces green leds 4 pieces.
Upload the code in the arduino uno and power it by using a laptop or the ac to dc adapter.
This code is very simple and should be easy to understand for most.
Red yellow and green led.
Similarly the traffic light controller will work for the signal 3 signal 4 and the system will keep looping.
We included a dial to change the green light time.
It is a simple implementation of traffic lights system but can be extended to a real time system with programmable timings pedestrian lighting etc.
If you re having trouble getting it there are some great tutorials on the arduino website.
Components required for arduino traffic light controller.
6 x 220 ohm resistors.
Arduino traffic light code.
The components you will be required for arduino traffic light controller are as follows.
Getting started with arduino.
We didn t use the delay function as a timer.
Arduino traffic light controller for kids toys.
Below is a short video that goes through all the steps to assembling and running the traffic lights using the 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 traffic lights works.
How to make arduino based traffic light controller.
So it is not time to write a basic arduino program to control these leds in a traffic light pattern.
