Digital Media Project

I have been doing research on the Arduino Micro-Controller board. Specifically I have been researching the electronics/wiring of the Arduino, which I am hoping will help me on my own Project.

The research was carried out by reading up on Arduino (using tutorials, MAKEZINE videos on Arduino project such as making an LED blink). These were vary helpful and thought me the the basics of the Arduino.

The inner workings
Through this research I have made some progress in learning the inner workings of the Arduino board itself, Resistors and Wires. This is what I have learnt so far:

The board
So far the main thing I have learnt about the Arduino board is the Input/Output Pins. It's still all a bit hazy at the moment, but I think I understand how they work. I found out that the Pins come in Digital, Analogue and Ground on the Arduino. I am not quite sure the difference between the Digital and Analogue pins quite yet. All I know is that different projects require you to use either Digital or Analogue pins. I will need to go into further research on this so that I can get a clearer understanding.

The Ground pins are used to wire/connect e.g. the LED ground signal to the Arduino. So far I know this is done so that whatever you are working with doesn't break.

Resistors
This is what I have learned about Resistors:

• They are used to controll the flow of electricity by resisting current.
• The resistance of "Resistors" are measured in ohms units, also written as this Ω.
• The bigger ohms a resistor has, the harder the flow of electricity gets.
  
• An easy way to think of a Resistor is like in Waterpipes, i.e. the flow of water current. The bigger a pipe the easier the resistance such as a firehydrant used to put out fires, and the smaller the pipe the higher the resistance such as a water fountain where people drink water from.
