    Light-emitting diodes (LEDs) produce light from electricity using semiconductor materials. They operate from a low DC voltage and produce little heat because there is no incandescent filament. They are available in a range of colours, with red, green, and yellow being the most common.

    The seven-segment number display (Figure \(\PageIndex{2}\)) uses one LED for each section to create different numbers from 0 to 9.
