orentation detection

a tile switch isn't going to do it... it needs to know what it's X and Y angels are and not just an on off signal.

Hi,
If the object (table in your case) is stationary, ie not accelerating in X, Y or Z then using an accelerometer should work fine.
If the table is going to move in X, Y or Z (like a Segway or self balancing robot etc) then using only an accelerometer won't work properly because it will pick up those accelerations as well and you won't know the real tilt angle.

hi henrik,
Thanks for that it is stationary, and i've found a chip that will work for me, ADXL345 from Analog Devices.
Now, the fun bit is writing the software for it...
