Hello all,

I measure a temperature with LM35DZ and Arduino and I would like to show this temperature in Labview. But I don't know how.

Could you help me?

Thank you.

You need to get the arduino to send the readings using the Serial.print() commands. Then in LabView you need to set up a serial input port, read the values and then display them.

Hi Mike,

I have tried to use this Arduino Connection (SubVI).vi from this page http://web.me.com/iklln6/automation/LabVIEW.html,  but Labview is ansvering with this error code -1073807246 and source Property Node (arg 1) in VISA Configure Serial Port (Instr).vi->Arduino Connection (SubVI).vi and nothing works.



I don't know what is wrong.

You have not configured the part of your VI that talks to the serial port to match what your serial port actually is on your machine. That is to how your machine sees your arduino.
