Raspberry and chips

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

Raspberry PI project Using PI 4 GPIO signals to control a 74LS00 NAND Gate Simple little project showing how NAND gate integrated circuit works. The circuit is built on a breadboard which will be connected to a Raspberry PI 4 using GPIO signals. Control GPIO Pins. The code to control the circuit is written in python. you can substitute a 74ls08 which is a AND gate, the output will result be opposite to the NAND gate. This can also be demonstrated by doing a SCRATCH. I will upload a SCRATCH set via sites.google.com/view/fxv300tech/

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.
