Maker “DJ’s Fantasi” is the technical director at his local high school’s theater arts program, and when the director of their winter production of Disney’s High School Musical requested a scoreboard prop, he excitedly set to work. 

The resulting build consists of four 7-segment displays, lit up by strips of non-programmable LEDs. 

Numbers on the device are shown with the help of an Arduino Mega, which takes input via a single-channel remote. Seven I/O pins are used to indicate each segment to be displayed, and another four multiplex the signal into the required four digits.

While a more general input device could be used, this particular scoreboard was especially set up for this musical, sequencing through numbers that correspond to the performance on command.
