For most LabVIEW projects, especially when you are new to LabVIEW, it is beneficial to start from a working example and modify the code to fit your needs. A microphone or mic is a very common input device used to input sound that is then stored in a digital form. It is very similar to the digital input type, but the hardware is capable of detecting rapid ON/OFF inputs. Every input should have at least some amount of time on and off. The top 2 numbers are the milliseconds delay on and milliseconds delay off for the input. The last pin on each digital input port connector provides a voltage (connected to the 5V power input, through a 10 ohm resistor and a diode) which is used by the Optocouple Input Terminal modules.
