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.
Traffic light controller using arduino code.
The circuit will look like the image shown below.
Almost any arduino will work for this project providing it has enough pins.
The code for this arduino traffic light controller project is simple and can be easily understood.
3 x 100 ohm resistors color brown black brown breadboard wires.
The main purpose of this project is if there will be no traffic on the other signal one shouldn t wait for that signal.
Below is a short video that goes through all the steps to assembling and running the traffic lights using the arduino.
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.
Apart from the basic arduino you ll need.
In this circuit 6 led s of three different colors are used to implement traffic lights at 2 way.
Program and working explanation.
So at start green light of signal 1 and red lights at.
Power up the breadboard using the arduino 5v and gnd pin.
This is not the real time traffic light controller.
6 x 220 ohm resistors.
In this project an arduino based traffic light controller system is designed.
1 x 10k ohm resistor.
The components you will be required for arduino traffic light controller are as follows.
Red leds 4 pieces yellow leds 4 pieces green leds 4 pieces.
I also made an density based traffic light controller using arduino.
Don t forget to take a look at that.
Working of arduino traffic light controller this project is done to give you an idea of how the traffic light controller works.
Red yellow and green leds.
Components required for arduino traffic light controller.
Now connect the leds to the arduino as shown in the circuit diagram below.
Red yellow and green led.
Similarly the traffic light controller will work for the signal 3 signal 4 and the system will keep looping.
Led 1 led 2 up to led 12 will be connected to pin1 pin2 up to pin12 of the arduino uno board.
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.
The equipment i have used in this arduino traffic light project is listed right below.
Although it is not the ideal implementation for real life scenarios it gives an idea of the process behind the traffic light control system.
What you need to build an arduino traffic light controller.
Upload the code in the arduino uno and power it by using a laptop or the ac to dc adapter.
