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. Project notes: https://sites.google.com/view/fxv300tech/raspberry-pi-4/projects/7-segment-display-project

Raspberry PI project 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 https://sites.google.com/view/fxv300tech/

I have soldered the 74hc595 to a piece of vero board. I Also soldered the resistors and LEDs. I connect 3 signals to the raspberry pi GPIO signals, DATA (14), shift CLOCK (11) and the data latch (12). The outputs q0-q7 are wired to an LED via a 330𝛀 𝒓𝒆𝒔𝒊𝒔𝒕𝒐𝒓

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/

Blinking Red LED on Raspberry PI 4 and Breadboard powering I had a Blinking Red LED on Raspberry PI so have now used an external power supply from an old DVD player. Have used the 12V via a voltage regulator to power up the PI 4 and also the breadboard for projects. !! re-use items from old units if you can.!! The wooden box housed an old power supply which is probably from year 2000.
