arduino prototype 3d model

A simple Arduino Uno prototype setup without any enclosure or box. The Arduino Uno board is clearly visible on a flat surface, connected to a breadboard with jumper wires. There are five large colorful push buttons (red, blue, green, yellow, white) connected with wires. There are also two LED indicators (one red and one green) connected through resistors. A small buzzer is included in the circuit. A USB cable is connected to the Arduino, going out to a computer. The wiring is simple, clean, and not overly complex, like a beginner educational project. The layout is organized and easy to understand, showing how all components connect to the Arduino. No box, no enclosure, no casing. Only the electronic components on a flat surface. Realistic style, clean lighting, suitable for an educational prototype demonstration.
