 Individual Components and their Uses
Note that components are sometimes characterized by their electrical characteristics ( resistor, capacitor... ) and sometimes by their use ( sensor ) and sometimes by other characteristics. This can mean that a component is listed twice. For example, a temperature sensing resistor is both a resistor and a sensor. We are listing in alphabetic order, but remember components may have various names.
Store charge and energy, block dc, filter. In their simplest form passive components, but now some are IC using switched capacitors to synthesize other and variable values.
Lots of people put a microprocessor and most of the other essential stuff on a tiny little demo board, easy to plug into your solderless breadboard (or your custom PCB) that has just a few more things that make your project special.
LEDs, photodiodes, optoisolators, LCDs, IR proximity detectors,...
Crystals, Ceramic Resonators, oscillators, ... Vibrate with excitement.
including Inductors and Transformers
Little Computers for your entertainment.
and Potentiometers Resistance is not futile. In there simplest form passive components, but now some are IC using forming variable resistors and potentiometers.
Diodes, Transistors are described here. These guys are the basic semiconductors or solid state electronics. ( But not Light Emitting Diodes = LED or Photo Diodes which are listed under Optoelectronics. )
Accelerometers, Gyroscopes, Temperature Sensors, Pressure Sensors, ... Find out what is going on.
Turn things on and off.
Make thing move. We include some circuits/chips for driving motors. Servos, steppers, and others.
GPS, Mobile Phone, RF Transceiver, Bluetooth Modules, ...
So many parts to pick, but which ones? Why not pick a popular part, or a group of parts for areas of interest?

 How to Store Components
 Data Sheets
You will want data sheets for you parts. Do not leave home, or start a project without them. Check:
- Electronic component From Wikipedia, the free encyclopedia
- Basic Components Quite a few components and some info on use.
