Individual Components and their Uses

What is an Individual Component? As we use it here it is more or less what we can buy 1 of. We used to think of this as a resistor, battery, bulb.... but the world has become more complicated. For quite a long time back circuits may have been built using per-built power supplies. We categorize these as Modules, now a large number of building blocks are available this way, Microcontroller Boards are but one example. Integrated circuits are another form of compound components, there are 100's of kinds. In this listing Integrated Circuits, Modules, Microcontroller Boards are listed as one item, but note that they come in a huge number of flavors with a huge number of purposes.

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.

Batteries

Power Up.

Capacitors

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.

Connectors

Join parts.

demo board

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.

Enclosures

Cover up.

Integrated Circuits

Op Amps, Voltage Regulators, Drivers, Digitally Programmable Potentiometers, 555 Timers ... For motor drivers see Motors below. Lots of parts in a package to do something useful.

Optoelectronics

LEDs, photodiodes, optoisolators, LCDs, IR proximity detectors,...

Oscillator

Crystals, Ceramic Resonators, oscillators, ... Vibrate with excitement.

Other Passives

including Inductors and Transformers

Microcontrollers and Microcontroller Boards or Modules

Little Computers for your entertainment.

Motors

Make thing move. We include some circuits/chips for driving motors. Servos, steppers, and others.

Modules

GPS, Mobile Phone, RF Transceiver, Bluetooth Modules, ...

Resistors

and Potentiometers Resistance is not futile. In there simplest form passive components, but now some are IC using forming variable resistors and potentiometers.

Transistors, Diodes, etc.

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. )

Sensors

Accelerometers, Gyroscopes, Temperature Sensors, Pressure Sensors, ... Find out what is going on.

Switches and Relays

Turn things on and off.


Popular Parts

So many parts to pick, but which ones? Why not pick a popular part, or a group of parts for areas of interest?
