Traffic light systems have been in use for over 100 years. However, urban mobility faces new challenges worldwide with rising population densities, expanding road networks, and increasing car ownership. Originally designed to manage traffic with minimal human intervention, today’s traffic light systems are expected to do much more. They now play a critical role in…
How to design an Arduino-based traffic light system
Traffic light systems are important signaling devices that regulate the flow of vehicles and pedestrians at intersections, crosswalks, and other critical areas. These systems use three primary lights — red, yellow (amber), and green — to manage traffic effectively and ensure safety. In this project, we’ll create a traffic light system for a four-way intersection…
