WHERE TO NOW?

All of my objectives were met. The unit works well at finding level and giving a number of feedback methods of current position. The unit would be useful for numerous other applications (e.g., a self-leveling platform). The LCD and graphics package will form the basis for future projects that I look forward to working on.

It would be nice to have a fully functional unit. Initially, I was planning to build a unit that looked like a hollowed out hockey puck and then mount the lot inside. The problem, however, was that the area that the sensor base was measuring was pretty small. Errors would have been introduced. If you are building a wall, then you probably want to know if the entire wall is level, not just one brick. A circular unit that reduces angular errors and gives a better overall impression of the angle would be more suitable. Something resembling a dinner plate might work.

I would also like to experiment with some of the higher-resolution AOSI sensors. Most of the high-resolution sensors tend to be single-axis, but they can be driven in a similar fashion.

One person who saw my project suggested that I create a game that would involve a moving circle on the screen (in Game mode) that represents a bouncing ball. When the ball is at its smallest, measure the angle sensor and then change the trajectory of the ball. The idea of the game is to keep the ball bouncing on the spot. Hey, the first mobile phone games were pretty lame.
