Parking Sensor Layout
Top-level parking layout showing how the entry and exit sensors frame the count-up and count-down path through the lot.
Diagram 07
Partition Overview
High-level architecture image that matches the project-partition PDF and makes the three-stage structure easier to discuss before drilling into the full schematic views.
Diagram 08
3D System Block Diagram
Top-level system block diagram showing the detector inputs, push-button controls, unit and tens counters, seven-segment displays, inverter and AND-gate logic, LED states, relay path, and NE555 flashing section in one 3D view.

3D Textured Hardware Render
Industrial-texture variant that keeps the full block-diagram path visible while turning the counters, displays, gates, LEDs, and warning path into a more physical hardware presentation.
Diagram 12
3D Labeled Hardware Diagram
Bright high-contrast variant that emphasizes the hardware names and signal directions across the sensor, counter, display, gate, relay, timer, and LED sections.
Diagram 13
3D Glass Panel Diagram
Wide glass-panel style render with routed trace-like links between the counters, displays, timer, relay, and logic stages for a more physical hardware-board feel.
Diagram 14
3D Minimal Hardware Diagram
Compact white-background render that still shows the full path from Stage 1 sensing to Stage 3 warning output, using stronger colored arrows between the major hardware blocks.
Diagram 15
System Concept Render
High-resolution concept render summarizing the IR gates, displays, major ICs, and the three-status LED outputs in a single visual reference.
