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.

The 4N35 is an optocoupler for general purpose application. It consists of gallium arsenide infrared LED and a silicon NPN phototransistor. What an optocoupler does is to break the connection between signal source and signal receiver, so as to
stop electrical interference.

Temperature sensor script using 74HC595 to output result to TIL311 display *

Image
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. The shift register is controlled via gpio output pins from a raspberry pi 4. All the documentation can be found at https://sites.google.com/view/fxv300tech/raspberry-pi-4/projects/74hc595-shift-register-project/ Raspberry PI 4 for many videos and projects visit https://sites.google.com/view/fxv300tech/raspberry-pi-4
