arduino based electronics 3d model

Create a realistic 3D prototype model of an Arduino-Based Automatic Main and Backup Power Switching System. The model should include: An Arduino Uno board mounted inside a small transparent control box A 10k potentiometer fixed on the front panel with a rotating knob Two SPDT relays placed beside the Arduino Two NPN transistors with base resistors clearly visible Two flyback diodes connected across the relay coils Two LED indicators on the front panel: Green LED labeled “Main Power” Red LED labeled “Backup Power” Power System Design: One “Main Power Line” shown above ground connected to a small street light pole (LED glowing green) One “Backup Power Line” shown underground through a visible soil cut section Wires should be color coded (Red = 5V, Black = GND, Yellow/Blue = Signal) Style: Realistic electronic prototype Clean wiring layout Educational engineering demo model Isometric 3D view White or light background Clear labels for components
