I have spent hours reading posts and following tutorials on this forum and this is my first post.
I had a bad experience earlier on in the year and ended up walking away from a project without getting it in any way finished, right now I am back with my box of bits and arduino, trying to find a solution to a problem that I thought would be straightforward. I was wrong and I need help from anyone in the know.
Step one of my current project is to acquire inclination from a sensor, specifically on a mitre saw, where i would like the angle of the saw to as precise a reading as possible,+ or - 45 degrees. Im after current angle, not what the saw moved. for instance iI would like a led to come on when the saw is at 30.1 degrees. I would like only one axis to begin with, but eventualy as the saw works on x and y plains, i too would like to be able to read 2 plains.
Having done a few hours on google it seemed an accelerometer was the way to go, now im not so sure. Perhaps the wii chip or an accelerometer with an added gyro?
Ive been using one of these http://www.ebay.co.uk/itm/New-GY-61-ADXL335-Module-3-axis-Analog-Output-Accelerometer-angular-transducer-/130933785328? Im getting serial readings of the xyz pins but have not found a good example or description of how to turn them to degrees.
I was able to follow this tutorial. http://chionophilous.wordpress.com/2011/06/20/getting-started-with-accelerometers-and-micro-controllers-arduino-adxl335/
Is there any hardware components out there that will output its current inclination in degrees without needing to be calibrated or converted?
Thanks in advance for any replys.
