DE0-Nano FPGA Tilt Sensing tutorial

Based on Adafruit’s Altera Cyclone IV FPGA starter board:

After building a 40 pin breakout board for my DE0-Nano I wanted to test it out with something fun but not overly complex. The DE0-Nano has an on-board accelerometer which can sense changes in acceleration and tilt, so I figured why not try to do something cool with it.
This article will show you how an accelerometer works, how it can be used to detect tilt and also how we can display that tilt ‘value’ visually on a large array of LEDs on my DE0-Nano breakout board. This way whenever we need to see if something is level, we can use this simple but fun tool to know, although don’t count on multiple decimal precision here!
