But watching a project shrink can be a real treat too, as early versions get refined into sleeker and more elegant solutions. This slimmed-down mechanical seven-segment display is a perfect ...

[Peter Lehnér] has designed a brilliant 7-segment flip-segment display that doesn’t really ... or pully scheme is built into your projects!

The project shows how a 7-segment LED can be interfaced and used in a PIC microcontroller project. 7-segment displays are used frequently in electronic circuits to show numeric or alphanumeric values.

This project is similar to Project 6 but here the microcontroller's timer interrupt is used to refresh the displays. In Project 6 the microcontroller was busy updating the displays every 10ms and ...
