NPN transistor

A two-junction (bipolar) semiconductor transistor with an N-type collector and emitter and a P-type base. An NPN transistor is formed by introducing a thin region of P-type semiconductor material between two regions of N-type material.

An NPN transistor is "triggered" when its base is brought high. Go here for more details on transistors in general; go here for a discussion of transistor usage in BEAM robots. Compare PNP transistor. Note that both PNP and NPN are TLAs.
