## Four-Way Traffic Light System Using CD4017 and 555 Timer IC

Four-Way Traffic Light System I’ll guide you through a project on designing a four-way traffic light control system using the CD4017 decade counter and the 555 timer IC. This project mimics a basic traffic light controller, cycling through red, yellow, and green LEDs for each lane in a timed sequence, just like a real intersection.…
