Arduino Relay Optocoupler at Cameron Silcock blog

Arduino Relay Optocoupler. Today in this tutorial we will see the interfacing optocoupler with arduino (4n35 or mct2e). 1m+ visitors in the past month You don't want to connect your relay module directly to your arduino, as it will eventually damage it. But before that let’s see what an optoisolator or optocoupler is? Optocoupler is also called an optoisolator. I want to activate the relay (that will active a solenoid valve) using an external 12v power supply and the arduino's 5v from a digital pin, in other words: In this instructable i will show you how to isolate and control the speed of a 12v pc fan with your arduino board, this circuit could be used to control many things with minor modifications to the circuit. Isolate the power rails from noise and spikes caused by emi/rfi during contact arc and from driving the relay coil. In the following post i have explained how to drive a relay by using an isolated method, or through an optocoupler device.
