Controlling 4N35 optocoupler using a GPIO signal from PI 4 or Arduino Controlling 4N35 optocoupler using a GPIO signal from Raspberry PI 4 or Arduino or any similar device which has General Purpose Input Output facilities (GPIO). Simple python script can be adjust for timing.

If you want to set a static TCP/IP IP Address for a Raspberry PI 4 you can do this fairly easily. You either set it up manually using Linux commands via terminal or use the GUI provided by Raspberry Pi OS

Controlling 4N35 optocoupler using a GPIO signal from PI 4 or Arduino.  These mini projects will get you creating circuits and understanding how they work. 

 Visit FXV300  for some of my PI 4 projects and their documentation. PI 4 to Breadboard project to read temperature and display on Segment display using python to write script Powering the Raspberry PI 4 and the breadboard using an old power supply from a DVD player. Temperature output project using a python script which outputs the temperature to two til311 segment displays. The segment displays are located on a breadboard and the data is transferred via a shift register, the 74HC595 Raspberry PI 4 project 74HC595 with 8 LEDS  4N35 Optocoupler Circuit.

 In August 2020 I purchased my first ever Raspberry PI 4 . This device is very versatile and can be used with a variety of operating Systems. The OS lives in an SD memory card and can be swapped out whenever you fancy a change.  Since then I have done several projects using the Raspberry PI 4
