I am working in a robotics project, concretely in an Autonomous Ground Vehicle.
I am interested in estimating the speed with a 3 axis accelerometer.
My main idea is interfacing the accelerometre (with a nice Analog output) and read it periodically using interrupts. Knowing the acceleration and the period of time between reads I guess I could estimate the speed (hard integration).
I just wonder if anyone has ever done speed estimation using an accelerometer in Arduino and if my suggestion is correct.
