educational toll booth 3d model

Photorealistic 3D render of an educational scale model of an intelligent toll booth system for a physics project, isometric low-angle view. The scene shows a straight two-lane road with a TOLL BOOTH STRUCTURE positioned ON THE SIDE OF THE ROAD (not in the middle). A LONG BARRIER ARM (toll gate) extends horizontally across both lanes, attached to an SG90 360° servo motor mounted on the toll booth, demonstrating automatic barrier operation. ALONG THE ROAD, there are FOUR DECORATIVE LED POST LIGHTS: two on each side, evenly spaced, with small LEDs on top glowing softly. The road has lane markings. The toll booth interior is PARTIALLY OPEN or has a cutaway wall to reveal the electronics: an Arduino Uno Mini board (blue PCB with silver USB port) with colorful jumper wires (red, black, yellow) connecting DIRECTLY to components (NO BREADBOARD visible). The connections include: - An SG90 360° servo motor (already connected to the barrier arm) - A sound sensor module (for clap-activated lighting) mounted inside the
