What happens when four laser beams meet four targets? In this creative engineering project, an Arduino Mega controls four laser modules that shine onto light sensors. Each detected beam activates a relay, driving a micro solenoid to strike its corresponding target. I enjoy building projects that combine software, electronics, mechanics, and creative design. Every build starts as a prototype, using simple components to explore new ideas and bring them to life.

4 lasers. 4 light sensors. 4 relays. 4 electromagnetic solenoids. Part 2 of my Arduino laser project!
