How to Make Traffic Lights Using Arduino Uno | Make Traffic Control System


Introduction

Vehicles moving on-road may cause unpredictable accidents leading to colossal loss of mass and life. But what is that causing the orderly movement of Vehicles? Traffic Control System. It is used to avoid accidents and to control the flow of traffic. In this project, we will be using Arduino Uno to control the timings of Led in each direction, and with this, we will guide our vehicles to move towards a particular direction. As we know, in the traffic Control System, the green led refers to move, Red is to stop, and Orange is to get ready or to slow down. We have considered Four Directions, When the Green led of Direction 1 is ON, this indicates that all the vehicles from Direction 2,3, and 4 should move towards Direction 1. Meanwhile, all the other directions i.e. those in which orange or green is not turned ON, have their red led turned ON. Afterward, Orange led of direction 2 turns ON, this indicates that all the vehicles from direction 1, 3, and 4 should get ready to move towards direction 2. After a delay (3seconds in this project), the green led turns ON and all the vehicles from directions 1,3, and 4 move towards direction 2. In a similar way, Orange led of direction 3 turns ON and then Green led after a delay of 3 seconds. The same happens for direction 4 and in this way, the Orderly movement of vehicles is ensured.


Required Components:

To implement this circuit, you need the following components:

1.      Arduino Uno

2.      Breadboard

3.      Jumper Wires

4.      12 Led (4 Red, 4 Green, 4 Yellow/Orange)

5.      12 Resistors (Any Value between 220-1kΩ)

Hardware Setup:

For detailed hardware setup, watch our complete project video at YouTube.

EndNote:

Using Arduino Uno, we were able to control the timings of led and hence successful in guiding the vehicles in terms of which direction to choose if a particular direction has its green led ON. We hope that you learned and enjoyed it.

  2. Not only can good lighting prevent theft and accidents, but a proper lighting design can also promote the health and wellbeing of your eyesight. If you enjoy reading or working on your computer, it is very important to make sure that your space is properly illuminated. ProTuningLab
