 +  * Terminology
 +<code>
 + Digital - Signal that is either on or off, typically binary 1 or 0. An example is an LED or an on off switch.
 + Analogue - Is a signal that can represent a lot of values. Like a microphone, speakers or anything that isn't easily represented by 1 or 0.
 + IO - Input/Output - These are the basic interfaces to the outside world of the micro, some are digital some are analog, some are able to be both input and output.</code>
