In conclusion, the traffic light controller using 8085 microprocessor is a simple and effective system for controlling traffic flow at intersections. The system can be easily designed and implemented using the 8085 microprocessor, memory, I/O ports, and traffic light signals. The system has several advantages, including flexibility, reliability, and cost-effectiveness.
