Calculates and displays the FFT of acceleration data. The strongest frequency is given as well. This is a great tool to analyze vibrations.
Measure the time between two or more sound events.

Set up a bunch of magnets as marker, so you can use this experiment to measure the speed and distance while moving along these magnets.
Calculates and displays the FFT of magnetometer data. The strongest frequency is given as well.
Measure the time between two or more acceleration events. This uses the accelerometer to trigger a stopwatch by (small) mechanic shocks.
Use the light sensor to measure times. You can set a threshold and determine the duration of brighter/darker states or the time between two bright/dark states.
Use the proximity sensor to measure times. You can determine the duration of close/far states or the time between two close/far states.
