This tutorial gives an introduction to the HY-M154 / 817 optocoupler module. Moreover, a simple application is programmed that shows how to wire and how to program an Arduino when working with the module. In electric circuits, we use mostly filters to remove noise. The circuit based on the capacitor and resistor always removes the noise from the incoming signal but the value capacitor and resistor always depend on the. An Optocoupler, is an electronic component that interconnects two separate electrical circuits by means of a light sensitive optical interface. The 1 Channel Way Optocoupler Isolation Module (Manufacturer: AC, Part ID: Optocoupler) is a compact and reliable module designed to provide electrical isolation between input and output circuits.
