Components of Vending Machine with respect to HLD
Building upon the High-Level Design (HLD), the Low-Level Design (LLD) explains each primary element, outlining how they make a contribution to the general capability of the vending machine system. For example:
- User Interface Logic:
- In the LLD, the user interface logic is broken all the way down to specify how the keypad or touchscreen inputs are processed.
- It details how the display unit is controlled to show off product information and transaction status.
- Payment Processing:
- This component explains how the machine checks if coins are valid, how it handles bills, and how it processes card transactions.
- It outlines the communication protocols among the software and the payment hardware components.
- Inventory Management:
- The LLD breaks down the inventory control machine, explaining how the product database is dependent and the way it is updated with sales and restocking activities.
- Dispensing Logic:
- The detailed plan (LLD) gives clear reasons for how the conveyor machine work.
- It also explains how the computer program controls the process of giving out products, making sure it happens in a specific and reliable way.
- Security Measures:
- LLD covers how tamper detection mechanisms (Tamper detection is the ability of a device to sense that an active attempt to compromise the device integrity , the detection of the threat may enable the device to initiate appropriate defensive actions) and encryption protocols are implemented to secure the vending machine.
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.
