void loop;setLed(int addr, int row, int col, boolean state);
I was wondering, how hard would it be to use a two axis accelerometer to control a small square on a LED matrix? I'm thinking of using an 8x8 LED matrix and lighting a box of 2X2 that moves around. So if the sensor was level, the box would be in the middle of the matrix, tilt it left and the dot moves left, etc. The further you move it to the left, the further the box moves. Easy project? (I'm trying to learn, still a noob, so don't get too technical on me please.)
