Liobaba D213 Opto-Isolator Breakout Board Module ILD213T Optoisolator Microcontroller

this is an optocoupler it's used to control circuits and we're going to learn how they work and also how to design some simple optocoupler circuits in this video optocouplers are integrated electronic components that look something like this they are also known as opto isolators optical isolators and photo couplers in this version we have the main body with four pins pin one is the anode pin two is the cathode pin three is the collector pin four is the emitter and we also have a small circular indentation in the body next to pin 1 and we use this to identify the different pins on the body we also have some text this is the part number we use this to identify the type of optocoupler and also find the manufacturer's data sheet this device is basically a solid state relay which interconnects two separate electronic circuits circuit one is connected across pins one and two the second circui
