In this tutorial we'll learn how to read the value from an analog pressure sensor and display it on a graph, then we'll modify the code to store the maximum pressure value and plot it on the same graph.

• Sparkfun Inventors Kit for LabVIEW Setup

• Sparkfun RedBoard
• 1x Pressure Sensor

• LabVIEW
• NI-VISA
• LINX

• Open the LINX - Analog Read 1 Channel example from the LabVIEW Example Finder.
  
  
• Select the AI channel connected to the pressure sensor.
  
  
• Run the VI, then press on the pressure sensor pad.
  
  
• Modify the VI to graph the current pressure as well as the maximum pressure recorded since the VI started.

• Use the pressure sensor to control LED brightness.
  
  
• Use the pressure sensor as a toggle switch to turn an LED on or off.
  
  
• Use the pressure sensor to control the tone of a piezo buzzer.
