The distribution of electronic components in labs and workshops is often done by hand, which can cause delays, mistakes, and wasted time. To overcome these problems, we designed a smart vending machine made especially for electronic parts like resistors, capacitors, LEDs, and ICs. The system uses a conveyor belt divided into sections and driven by a stepper motor, allowing it to release one component at a time with high accuracy. Users can choose the needed part using a 4×4 keypad, and an LCD screen shows the selection and current operation. This setup saves time, reduces human effort, and minimizes errors. In the future, it can also be upgraded with IoT features for automatic inventory tracking. The machine is affordable, reliable, and easy to expand, making it suitable for use in colleges, electronics shops, and manufacturing units.

Conclusion
The smart vending machine for electronic components offers an efficient and innovative way to overcome distribution challenges in labs, workshops, and stores. Its microcontroller-based system, combined with stepper motor control, ensures precise and reliable dispensing. The setup saves time, minimizes human errors, and improves component management. Unlike earlier designs that were either too simple or overly complex, this model provides a balanced solution that is affordable, dependable, and easy to upgrade. With future integration of IoT features for inventory tracking, the project demonstrates how basic automation can significantly enhance everyday operations in both educational and industrial systems.
