Abstract

The paper details the mechanical, electrical, and programming for designing and developing a multi-functional adjustable desk with automated height and tabletop tilting capabilities. The electrical system, featuring an Arduino Mega microcontroller, reads inputs from a control panel to control the linear actuators for height adjustment and a stepper motor for the unique tilting feature. Through rigorous testing, the desk achieved smooth, synchronised movements and reliable positioning at any height or angle. The work undertaken highlights the importance of motor control optimization. Additionally, the prototype achieved an error range of less than 1% for the zero-degree operation, and less than 1.5% for the ninety-degree operation. The developed desk is a high-quality, robust solution that integrates seamlessly into diverse working environments.
