20 sty 2022 · PC817 Arduino Project (image credit: https://www.instructables.com/Isolating-circuits-from-your-arduino-with-optocoup/) Above is an Arduino interface circuit wiring example based on the PC817 optocoupler, the Arduino Uno Board, and the 2N2222 transistor.
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!
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”.
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.
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.
