Controlling 4N35 optocoupler using a GPIO signal
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.
7 Segment display project - Raspberry PI
7 Segment display project - Raspberry PI This project uses a chip with 4 by 7 Segment display and a decimal point. The unit is controlled via GPIO pins and is fairly easy to wire up using a breadboard. There are many 7 segment display chips available. KYX-5462BS, HS-3461A are a couple of examples. Code written in Python. KYX-5462BS, HS-3461A, Raspberry PI, Raspberry PI 4, 7 Segment display
