Hello!! So today I had to figure out how to read the capacitance of each and every ultrasonic transducer on the speaker array. There are several ways of accomplishing this task. 1. Buying a capacitance meter 2. Using an oscilloscope and calculating it 3. Build one on your own using a AVR microcontroller, using this http://blog.makezine.com/2008/06/24/arduino-capacitance-meter/ and this http://arduino.cc/it/Tutorial/CapacitanceMeter as a reference. I have chosen option 1 since it is the simplest method and least expensive.
