Arduino KY-008 LASER module

Описание

Hi, welcome to this fast tutorial about the KY-008 Laser module, here as you can see I only used only 2 pins, I may be wrong, some use 3 pins instead for current limiting or something... correct me. hope you like it.

(It's not a much tutorial but I wanted to do it before to include it in a project as always).
