11 maj 2024 · Learn How to interface a PC817 4-Channel Optocoupler Module with Arduino. using PC817 Module example code, circuit, pinout library.
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. So lets get started!
4 sty 2020 · The circuit first steps down a 24 VDC input to about 3.7 VDC using a 150 kΩ resistance and a 5.1 V Zener diode. This 3.7 VDC is fed to the input of optocoupler PC817 pin 1 and 2. On the output, I wanted to read the high and low through an Arduino connected to pin 3 and 4 of the optocoupler.
20 sty 2022 · The PC817X series optocoupler IC is comprised of an IRED (Infrared Emitting Diode, or IR LED) and a phototransistor optically coupled to it. It functions as the inner phototransistor conducts when receiving the IR LED's emitting light.
30 kwi 2021 · 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 this tutorial, the module is used as an “digital input board”.
21 lip 2020 · In this tutorial, we are going to make a circuit of the Optocoupler Relay Driver. Optocouplers are electronic components that are used to transfer electrical signals between two isolated circuits by using light. They prevent high voltages from affecting the circuit receiving the signal.
