Traffic light controllers are an essential part of modern transportation systems, ensuring the safe and efficient flow of traffic at intersections. The use of microprocessors in traffic light controllers has become increasingly popular due to their flexibility, reliability, and cost-effectiveness. In this article, we will discuss the design and implementation of a traffic light controller using the 8085 microprocessor. 02H OUT 02H
