As part of our Make: Arduino page, Riley Porter has posted a project that shows you how easy it is hook up a 7-segment LED display to your Arduino projects. This is the first, simplest method he explores. In a future project, he’ll show you more elegant solutions that don’t hog so many I/O pins.

And as with the RFID Reader project Riley posted, this is really a project stub. We’re hoping others who have used such displays on their ‘Duino projects will add their experiences, tips, images, etc. to the project. Make: Projects are living documents. Help them grow!
