Jargon buster

Plain-language definitions for the technical terms used above.

phototransistor
A light-sensitive transistor that changes its electrical output when light hits it. Compared with a modulated IR receiver, a simple phototransistor can be more affected by ambient light, so it may need extra filtering or careful setup.
