Control Analog Out, Digital Out and Pulse Out
Recommended for grades 9–14.
Introduction
In this exercise, you will create a program to control the SensorDAQ’s analog out terminal (this is pin 9 of the screw terminal connector). In addition, a voltage probe will be used to read the voltage of the analog out terminal. The Analog Express VI is a simple way to program data collection from a Vernier sensor. The DAQ Assistant Express VI is a simple way to control the SensorDAQ’s screw terminal channels. Steps will be taken to modify the VI to control the digital-out line and the counter line.
Objectives
In this exercise, you will
- Create a LabVIEW VI to control and measure the screw terminal analog-out line.
- Modify the VI to control and measure one of the four digital-out lines.
- Modify the VI to control and measure a pulse train output from the counter line.
- Learn to use DAQ Assistant.
