Diode

• A semiconductor device with two terminals, typically allowing the flow of current in one direction only.

• Blocks the current that flows in the opposite direction

Zener Diode

•  flow in the forward direction as normal

•  but will also allow it to flow in the reverse direction

Light Emitting Diode

IR LED

• An IR LED, also known as IR transmitter, is a special purpose LED that transmits infrared rays in the range of 760 nm wavelength.

• Used in Remotes control.

Photodiode

• A photodiode is a transducer that takes light energy and converts it into electrical energy.
