Electronics is one of the main areas of robotics and it is essential to get a good grounding in electronic principals. The following sections will introduce you to the most common electronic components and why they are so useful.

Resistor
|
|
|
A Resistor restricts the flow of electric current. A simple circuit can be constructed from a battery, and Light Emitting Diode (LED) and a resistor; the resistor would be used to limit the current passing through the LED.

|
Capacitor
|
|
|
Capacitors store electrical charge much like a battery, although much simpler as they only store charge and do not produce it. Capacitors are used in circuits where a temporary 'Reservoir' of charge is required or where unwanted charge needs to be handled, such in power supply filter circuits.

|
Transistor
|
|
|
Transistors are semiconductors used to amplify or switch electrical currents.
|
|
|
Diode
|
|
|
A diode is a semiconductor which allows electrical current to flow in one direction and stops flow in the opposite direction.
|
|
|
Integrated Circuit (IC)
|
|
|
An Integrated Circuit, or IC, is a small electrical device that contains a miniaturised electronic circuit.
|
|
|
Light Emitting Diode (LED)
|
|
|
A Light Emitting Diodes, or LED, is small light-bulb based on a diode. LEDs are being increasingly used in electronic devices as they are very efficient, producing very little heat and much light compared to other traditional light bulbs.
