 Due the output of the sound sensor span from 0 to 1023 a simple conversion is needed in all cases in order to make the mapping to the motor power with a maximum of 100.

 By repeatedly tuning the minimum power we found that a minimum power of 40 was sufficient for this setup. With 40 as minimum power the motor power range is limited to 60 and the equation will therefore be
 
 *conversion factor = 60/1023 = 0.059*
+
 *power = (sound level * 0.059) + 40*
 
 This is implemented as a function which takes the sound level (0-1023) as parameter and returns the motor power (40-100). The implementation of this is seen in the following code snippet
