I am currently working on a project where I would like to measure X/Y inclinations changes, without worrying too much about the acceleration. I decided to use ADXL335 accelerometers in order to measure static changes of g ! To give a little bit of background, the project aims to use the Arduino Leonardo as a mouse, where the X/Y movement will be the readout of the ADXL335 placed on an object.
However, I'm now facing some issue with the reading resolution. In fact the object only provide angle inclination of +/- 10° from its 0 position, and the increments value from 0° to +10° does not provide enough steps to move the mouse from let say 512px on the right (1024 width resolution).
My question is : first, do you reckon any solutions using the actual sensor I have ? Smart coding or anything you could propose would be welcome. If not, what solution would you suggest ? I've been looking into inclinometer, but those 0,0031° resolution sensor are very very expensive ...
Thank you very much for your help !
