This project shows how to use the Raspberry Pi to drive a 7 Segment Display with the help of a 74HC595 chip. Parts used in this project: Breadboard Wiring cables (Male-Male, Female-Male) 7 Segement display (it actually has 8 segments because of the dot) 74HC595 Chip Raspberry Pi Revision 2 some Python code Here is […]

A serial-to-parallel shift register (or SIPO: Serial In Parallel Out) lets you take a sequence of signals on one output, and split them up into several separate outputs. For example, if you don’t have enough GPIO pins on your Raspberry Pi, Arduino, or other computer/microcontroller, you can use a shift register to add more. In

In my last instructable, I covered how to run a shift register using a Raspberry Pi, and kind of hinted that one thing you could do with it is run an HD44780 based display. That’s what this instructable will cover. This instructable is also the third one in a series leading up to my long

This instructable will attempt to explain, in simple terms, what a shift register is, and how you can use it with the Raspberry Pi to expand the GPIO port by running eight outputs with just four GPIO ports. To start with, what is a shift register? Wikipedia has a technical definition of shift registers, but
