This paper will describe some of the general usage of MATLAB's Data Acquisition Toolbox (DAT). The software in the toolbox allows MATLAB to acquire data from sensors and to send out electrical signals that can be used to control or drive external devices. The authors will be using this toolbox with two different pieces of hardware. One is the sound card built into the laptop, the microphone and speaker will serve as the data acquisition (And output) devices. The sound card provides convenience because it will allow testing the DAT outside of the lab.
