Revolutionizing Urban Mobility: Smart Traffic Light IoT Concept

Draw a smart traffic light IoT project concept. The system consists of a modern traffic light pole at an intersection, connected to a small control box labeled “ESP32 Controller”. Nearby, there is an ambulance with a GPS system sending its location to a cloud server. The server communicates with the traffic light controller to turn the red light to green when the ambulance approaches. Show wireless communication signals between the ambulance, the cloud, and the traffic light controller. The scene should look modern, with clear labels and arrows explaining the system’s process. Add icons for IoT, GPS, and cloud server.
