Stop Coding! Build a Full Traffic Light System with Only Logic ICs | Traffic Light Control Circuit
Building a real-world traffic light system doesn't always require an Arduino or complex programming! In this video, we dive deep into the "raw logic" of electronics. Using the classic 555 Timer and the CD4017 Decade Counter, I will show you how to design and simulate a fully functional Red, Yellow, and Green traffic signal in Proteus.
What you will learn in this tutorial:
How to generate a clock pulse using a 555 Timer in Astable mode.
How to use the 4017 IC to count pulses and sequence outputs.
The role of Diodes as "OR gates" to control the timing of each light.
Step-by-step wiring and simulation tips to avoid common circuit errors.
Whether you are an engineering student or an electronics hobbyist, this project is the perfect way to understand how automated systems worked before microchips took over. No code, no compilers—just pure hardware logic!
