 1 Using Arduino / Sensors / Re: ADXL335 Accelerometer on: May 27, 2011, 05:32:25 pm Hi AWOL,Thank you for your help... I think that i need explore more about reading analog values from Arduino. I think that the Arduinos Forum (http://didier.longueville.free.fr/arduinoos/?p=1389) will help me.But... one more question. The raw values that i receive from X axis are:-90º - 2560º - 32190º - 385Is correct make a Lookup Table? I have to calculate the factor from 321 to 385 and from 321 to 256, and then make the calc.Thank's again.
 2 Using Arduino / Sensors / ADXL335 Accelerometer on: May 26, 2011, 12:49:41 pm Hi,I have readed some posts with tilt measurement of ADXL335 accelerometer and i can't find the solution to calculate inclination angle.Because i use Arduino Duemilanone with 3.3v and i read http://www.freescale.com/files/sensors/doc/app_note/AN3107.pdf, to calculate the inclination angle I have to use this formula:angle=asin((Vout - 1650) / 330)This is correct? I don't thing so, because the result is always 0.Furthermore, my reads from x and y is about 324 and 345, so, with this values never i have a positive value.Can you help me please, find the solution?Thanks in advance.Rolando RochaFrom Portugal
