I'm new to ECE stuff, but I was wondering what kind of equipment I'd need to have an 8x8 or mor grid of lasers being controlled with specific on/off patterns. I'd want 5mW lasers in an 8x8 grid. It seems like I need an Arduino/Raspberry Pi, breadboard, wires, power supply, 8x8 matrix (or make one myself) laser diodes, collimating lenses... Does this sound about right? I see lots of articles for LED multiplexing, but nothing for lasers. Is there a substantial difference?
