Capacitor Photosensor Ultrasonic sensor Thermo sensor

PING))) Ultrasonic Distance Sensor The PING))) sensor emits short bursts of sound and listens for this sound to echo off of nearby objects. The frequency of the sound is too high for humans to hear (it is ultrasonic). The PING))) sensor measures the time of flight of the sound burst. A user then computes the distance to an object using this time of flight and the speed of sound (1,126 ft/s).

Description A transistor is an electronic component that can be used as an amplifier or switch. When a little bit of current/voltage is put into the Gate, a lot of current can flow from the collector to emitter (GENERAL DESCRPTION)

When the gate is negative,it repels the electron in the N-channel. So there is no way for electrons to flow from source to drain. When the negative voltage is removed from Gate,the electrons can flow freely from source to drain. So the transistor is on. JFET

Wiring Follow electricity path What is resistor for? Where does power come from?

Measure resistor when it is NOT in a circuit (value in Ohms)

Measure voltage of a battery using + and – ends (value in Volts)

Measure current in Amps

Measure voltage drop in Volts
