This is a project for Arduino to make a 2D Level, aimed at beginners.

Arduino draws a circle on an LED Matrix that moves around according to readings from a 2D Accelerometer.

Objectives:
* Learn how to draw a circle using simple Maths
* Learn how to use the LOL shield for the Arduino
* Learn how an accelerometer works

Step 1: What you need

<p>what is the purpose of drawing a circle instead of a single dot?</p><p>from the level use case point of view, a single dot will be well enough, no? (maybe I missed some point).</p>
