How to Build an Optocoupler Circuit
In this project, we will go over how to build an optocoupler circuit so that we can create electrical isolation of the input and output of a circuit.
Optocoupler Tutorial for Beginners
In the example below, an Arduino Uno controls a DC motor via an optocoupler. From the Arduino''s point of view, it is only controlling a simple LED. But the LED inside the optocoupler

Using Opto Couplers
The main purpose of an optocoupler interface is to completely isolate the input circuit from the output circuit, which normally means there will be two completely separate power supplies, one for the input
Optocoupler Tutorial and Optocoupler Application
An optocoupler can be used with both DC and AC signals with optocouplers utilizing a SCR (thyristor) or triac as the photo-detecting device are primarily designed for AC power-control
