The light-emitting semiconductor material determines the LED's color, so the number of colors is infinite. As indicated by its full name â Light Emitting Diode â an LED is a diode that emits light. A diode is a device that allows current to flow in only one direction. Almost any two conductive materials will form a diode when placed in contact with each other â with a single p-n semiconductor junction between them.

Other fun facts I learned about Texas as I was browsing for information about Texas Longhorns was that Texas Boots were designated as the Official State of Texas Footwear symbol in 2007, Square Dance as Official State Folk Dance in 1991, and Rodeo as the Official State Sport in 1997 [4].
