[tps_title]Make a huge 7-segment digital clock with Arduino[/tps_title]
Project by Matt Wes from Instructables dot com.
One of the benefits of the Arduino development platform is the ease of making an accurate clock, and the following example by Instructables member Matt_wes is not only easy to make but also quite useful.

Instead of making do with pocket-sized LED displays, this clock uses digits that are 16 cm tall and would be visible from quite a distance away. Thanks to the power required for each segment, they are switched via MOSFETS to deal with the current.
