Paced breathing controller using LabView

Paced breathing devices are designed and used for exactly that paced breathing. Often when a researcher is conducting an experiment that requires biological signals to be analyzed, the number of variables are reduced by keeping all of the subject´s rate of breaths per minute (BPM) the same. Presently there exists both software and hardware that serves the purpose for this task. This project has combined both of these to build a new apparatus using the latest technology. Instead of a hardware device which is difficult to manipulate once constructed, the software package LabVIEW (Laboratory Virtual Instrument Engineering Workbench) Is used to construct this device. LabVIEW is a icon driven package which parallels actual electrical components. If the situation arises in which changes need to be made, they can be performed relatively easily assuming there is some knowledge of the software at hand. The convenience of this arises because manipulations can be made without the use of a soldering iron or any other tool with the exception of a mouse
