Traffic management systems are essential for controlling car flow and guaranteeing pedestrian safety in metropolitan settings. The goal of this project is to build a basic yet functional traffic light control system utilizing easily accessible electrical parts, such as the CD4017 shift register and 555 timer. The CD4017 functions as a decade counter to cycle through the traffic light phases, while the 555 timer is used to provide the required timing pulses. This blog article will walk you through the necessary parts, the circuit schematic, hardware testing, Proteus simulation, and finish with insights into the real-world use of the project.
