Components of Vending Machine Low Level Design
The Low-Level Design is going beyond the HLD by way of presenting an exhaustive breakdown of every element:
- Coin Mechanism:
- Details how the coin mechanism interacts with the software program, which include validation and processing of inserted coins.
- Bill Acceptor:
- Describes the conversation and validation method involved in accepting paper currency.
- Card Reader:
- Explains how the card reader interfaces with the software program to authorize credit score or debit card transactions.
- Conveyor System and Spiral Mechanism:
- Specifies the control mechanisms for transporting merchandise and rotating the spiral for dispensing (a spiral mechanism refers to a specific design element used for dispensing products.
- It typically involves a spiral-shaped structure, often made of metal or another durable material, that rotates to move items from their storage location to the dispensing point).
- User Interface:
- Breaks down the input handling and show control logic for user interaction.
Vending Machine – Low Level Design
Vending machines have become an essential part of our everyday lives, offering various kinds of products starting from snacks and beverages to personal care items. While their capability can also appear simple from a user perspective, the low-level design of a vending machine includes complex info to ensure clean operation, robustness, and safety. In this article, we will dig into the low-level design of a vending machine.
