This article describes work related to the design of an embedded motorized positioning controller, focusing on motion control, user interaction, and serial communication.
The system is based on an ATmega2560 microcontroller, responsible for motor control, user interface management, and external communication. A local LCD interface provides real-time feedback such as position information, system status, and movement state.
The controller supports two operating modes.
A local mode allows direct manual control of the motors through the interface, useful for setup or adjustment tasks.
A remote mode enables automated control via a UART serial link, allowing an external system to command positioning sequences programmatically.
Motor control logic is designed to ensure repeatable and predictable positioning, with clear separation between motion handling and interface logic.
Overall, the work focuses on integrating motor control, human-machine interaction, and serial communication into a compact embedded controller suitable for automated positioning applications.
