Traffic Light Control Project using Arduino
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards can read digital & analog inputs from the sensors. With Arduino, you can write and upload computer code to a physical programmable circuit board (commonly called a microcontroller which is ATmega328P 8-bit Microcontroller) using a piece of software called the Arduino IDE (Integrated Development Environment), which runs on your computer.
The Arduino is the most widely used open-source microcontroller board for numerous electronics and do-it-yourself projects. The Arduino traffic light controller is a simple project. Nowadays, everyone desires to drive their own car. As a result, the number of cars on the road is constantly rising, resulting in traffic bottlenecks.
A traffic light controller assists in traffic management and traffic control. These devices are installed at road crossroads or crossings to prevent traffic congestion and accidents. The systems alert the motorist by employing various colours of light. As a result, avoiding congestion at junctions is straightforward.
In this project, we are going to make a traffic light control for a four-way intersection. We will learn about traffic lights and how they work through an electronic project. This project is a condensed version of the four-side or direction traffic light system that we have exhibited.
