A lovely PCB and classic Boldport instructions(!):
This project is a challenge to construct.
The Boldport 3x7 is essentially a 3-digit common-cathode 7-segment display, rendered with discrete components.
Since it’s a chance to look inside the workings of a 7-segment display unit, I decided to modify my build to flip the lid and expose the internal wiring for inspection. Now it’s built, more projects to follow!
As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub
