Modbus RTU RS485 Relay Module

This project showcases the use of a 32-channel RS485 relay module and Modbus RTU communication to automate drink dispensing in a vending machine. Customers can select their drink via a Windows app interface, which triggers the corresponding relay to release the beverage. By leveraging Modbus RTU and RS485, this system delivers reliable, scalable, and efficient communication, making it ideal for industrial applications. This setup combines robust automation with user-friendly operation, streamlining the vending process.
