Electronic Components
Diode
Diodes are like a one-way valve, allowing current to flow in a single direction. Diodes are typically marked with a line indicating the side of the ground pin.
Resistor
Resistors limit the flow of current. They vary in how much they limit the flow of current, which is conveyed in the form of coloured bands.
Light-Emitting Diode (LED)
Light-Emitting Diodes (LED) are like mini, low-powered light bulbs. They have two (or sometimes more) pins, and as they are diodes, these pins allow current to travel in one direction only.
Transistor
Transistors are simple, essential components of just about every electronic device today. In essence, a transistor allows one charge to control the flow of another. In other words; when one of the pins (the middle one) receives a charge, it allows a current to flow between the other two.
Motor
Motors are mechanical devices capable of deriving motion through electro-magnetism as current is applied to a coil of wire contained in the chassis of the motor.
Servo
Servos are a form of motor which allow very accurate movement (by degrees). They usually contain a motor component and a sensor component (to determine the precise adjustments needed for angular granularity).
