Video projector serial multimedia control unit using arduino (RS232)

In this project, an ordinary video projector was controlled using serial commands (RS232) via an Arduino Mega. Operation through an external custom-made 3D printed multimedia panel fitting into a 50 mm cable channel eliminates the need for the proprietary infrared remote control. The cost of the equipment was reduced by 80% compared to a commercial solution and is highly customizable. The secondary objective of the installation was to provide the user with a simple, unambiguous control panel that is completely reliable. The project presented covers the entire work-through process from analysis and planning to installation and the finished result.
