View or log output from your accelerometer sensor. The app has six screens to choose from: Meter This show the output from the accelerometer and minimum and maximum vales recorded. Graph Plots the accelerometer output over time. Option to save data. Spectrum Shows the frequency spectrum of the recent accelerometer data. Use to find resonant frequency's. Light Converts the accelerometer sensor output into a colour. Wave the device around and the colour will change. Music This is a musical instrument based on the accelerometer sensor. Orientation selects the note and pitch the volume. It is based on a 5 equal temperament notes per octave scale so that the music will still sound reasonable even if played badly. Info This screen provides info on your sensor, such as vendor, version, resolution and range. It also shows info for other sensors on your device. Write external storage permission so that you can save the data in graph or spectrum modes.
