PiezoBuzzer using USB DAQ

Goal is to use the NI DAQ inherited from MNS for triggering the piezo buzzer.

The DAQ comes with

Installing the DAQ on Ubuntu

Does not work. Switched to Arduino Uno.

Creating sounds with Arduino

Using the toneAC library for Arduino, we can get 10V pp sounds on the piezo. (The modulate the 9 and 10 pins which can do PWM out of phase to create a larger potential difference than the maximum 5V for normal Pin out.)

If this is sufficient amplitude, we should be able to trigger the sounds from the arduino, as well as the camera.
