Horizon-Oriented Laser Output

HOLO (Horizon-Oriented Laser Output) is an embedded system that automates directional pointing using azimuth and altitude coordinates. The system employs a master–slave Arduino architecture where user input is received via a keypad, displayed on a MAX7219 serial display, and transmitted through I2C communication to control dual servo motors using PWM. An interrupt-driven laser module enables real-time activation without delay. The system was validated through Proteus simulation and physical hardware implementation, achieving accurate and efficient automated pointing with minimal human intervention.
