text: Therefore the transistor is switched to “Fully-OFF”.

text: The transistor can be switched ON or OFF by changing the base.
text: Then the transistor is switched OFF.
text: Now the transistor is switched ON, the collector current flows and bulb lights up.
text: When the transistor is switched ON, a large collector current flows through the device between the collector and the emitter terminals.
text: Therefore, a transistor can be switched on or off by varying the voltage applied to the base terminal.
text: When a transistor is switched on or off, it does not immediately switch from a non-conducting to a conducting state; and may transiently support both a high voltage and conduct a high current.
text: You can interpret that arrow in a couple ways: it's the direction of positive current flow (opposite of electron flow), and also as pointing toward the lower voltage when the transistor is switched on, i.e. for an NPN the emitter has to be at a lower voltage than the base/collector in order for it to conduct, whereas for a PNP it has to be higher.
text: This configuration allows the transistor to be a switch, closing and opening rapidly like an electronic gate, allowing voltage to pass at a determined rate.
text: At its most basic, a transistor is a switch.
text: At its most basic, a transistor is a switch.
text: Since the PIR motion sensor outputs current and the transistor is a switch that turns on by electrical current, it's a perfect switch that works complementary with the transistor.
text: Since a transistor is a switch, it can be driven with a PWM signal.
