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
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
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
Transistor
Transistors are semiconductors used to amplify or switch electrical currents.
Diode
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)
Integrated Circuit (IC)
An Integrated Circuit, or IC, is a small electrical device that contains a miniaturised electronic circuit.
Light Emitting Diode (LED)
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.
