arduino code : for each

1. 8x8 Matrix Module: Read the following and use the library to run the 8x8 Matrix Module:

http://playground.arduino.cc/Main/LedControl

You need to learn and demonstrate two things:

How to turn on and off any arbitrary LED - for example blink the LED on Row 2, Col 3.

How to create any arbitrary figure like a smiley face, heart, letter, or number.

2. Joystick and Auto-calibration: Leave your 8x8 Matrix Module hooked up and also hookup your joystick. Write the following code to run the joystick and demonstrate it:

First, just continually output the values you get from the ADCs on the serial monitor for the X and Y axis to check that your joystick is working. Something like this: X=12, Y=217.

Next, modify your code in A by using auto-calibration and the map commands so that your X and Y axis display from 0 to 1023 exactly.

Finally, modify your map commands so that the X and Y axis output the integers 0-7 when moved from minimum to maximum.
