Planning to replace Components now in ComponentsOld

Individual Components and there Uses[edit]

Note that components are sometimes characterized by their electrical characteristics ( resistor, capacitor... ) and sometimes by there use ( sensor ). 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.


Power Up.


Store charge and energy, block dc, filter. In there simplest form passive components, but now some are IC using switched capacitors to synthesize other and variable values.


Join parts.

demo board[edit]

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.


Cover up.

Other Integrated Circuits [edit]

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.


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


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

Other Passives[edit]

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.

Transistors, Diodes, etc.[edit]

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.

Switches and Relays[edit]

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, ...

Popular Parts[edit]

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

Where to Components Come From[edit]

Component Manufacturers[edit]

Links to homepages, phone numbers, contact info, ... There is often info under each component as well in the components sections above.

Free From Salvage[edit]

Dig in, to the free stuff, a list of links and a bunch of ideas on how to use your loot.

Free Samples[edit]

Free is nice.

PCB Manufacturers[edit]

contact info, PCB trace width/spacing capability, ...

Salvage Ideas[edit]

Unusual ideas for the fruits of your labor.


Good places to buy, numbers to call, people to talk to, ... Get your low cost motor controller boards & motor driver ICs

How to Store Components[edit]

Component and Parts Storage

Data Sheets[edit]

You will want data sheets for you parts. Do not leave home, or start a project without them. Check:
