Traffic Light System using Arduino

In this video, we’ll build a Traffic Light System using an Arduino and an I2C LCD Display. This project simulates a traffic signal controller for a three-road intersection, where the signals automatically change with green, yellow, and red lights. We’ll walk through the components used, explain the code that powers the system, and demonstrate the working model.
Components Used:
Arduino Uno
I2C LCD Display (16x2)
Red, Yellow, and Green LEDs for each road
Jumper wires and resistors
No need to dive deep into complex diagrams-just a simple, step-by-step explanation of how to set everything up and get the system running.
If you’re looking for a beginner-friendly Arduino project or want to learn more about traffic light systems, this is the perfect project to start with!
