Using 3461 7 Segment 4 Digit LED for CPU Temperature Display with Python and GPIO on Raspberry Pi

A project to demonstrate how to control a 3461A/B 7 Segment 4 Digit LED display using Raspberry Pi GPIO and Python scripting.

Practical information including simple electronics theory to allow the project to include other displays of the same type, and other GPIO hardware such as breakout boards or HATs

The attached Digit Mapper (excel file) shows all possible alpha characters that can be shown by a 7 segment display, but also gives the ability to map the GPIO pin states required to show custom characters based on input by the user.
