If you are thinking about building your next project around a 4-digit seven-segment display, you need at least 12 connecting pins to drive all the segments properly, that is most of the pins for a microcontroller like Arduino. The workaround for this problem comes in the form of an IC, and as the title of the project suggests it's called TM1673 LED Drive Control.
