7 Segment Display
A 7 segment LED is a digital display module specialized to display numerical information. Light-emitting diodes (LEDs) arranged in the shape of numbers offer an easily visible display. They are sometimes called “seven-segment displays” or “seven-segment indicators.”
A 7 segment display is made of seven different illuminating segments. These are arranged in a way to form numbers and characters by displaying different combinations of segments. The binary information is displayed using these seven segments. These LED’s or LCD’s are used to display the required numeral or alphabet.
