The purpose of this laser diode tutorial is to provide the information necessary to create a long lifetime, stable laser diode system. Learn how to connect and control a laser diode module using Arduino in a few simple steps. This application note will introduce ROHM's LD line-up and show how to design the drive circuits of ROHM LDs.

An optocoupler, also known as an opto-isolator, is an electronic component that transfers electrical signals between two isolated circuits using light. In this guide, you'll learn how they work and how you can use one in your own projects. It typically consists of an LED (light-emitting diode) and a photodetector, such as a phototransistor, housed within a single package.
