You can learn to connect and program a laser diode with Arduino in this tutorial. This is helpful for finding objects or lining things up in electronics projects. The steps in this tutorial are simple, so beginners can do them. A laser diode is a cool component that you can do a lot of fun stuff with, from engraving wood to creating a light show or giving your robot eyes! They range from super cheap (or even free if you can find one in an old CD player!) to more expensive. Most types are really easy to use too, once you. 📦 For purchasing, use the RP Photonics Buyer's Guide for yellow and orange lasers. A laser diode makes a narrow beam of light.
