4)Ĥ.6 If the bytes at port are greater than 0, the “True Case Structure” will be activated and the VISA Read will return the bytes read.Ĥ.7 VISA Configure Serial Port should let the user choose which serial port to use and set up the baud rate, so “ Visa resource name” and “ Baud Rate” must be a control. To activate the Reading case, it has to check if the bytes at serial port are greater than 0 using a Programming > Comparison > Grater than 0 VI. The example above, you gotta choose the COM Port first before running the vi, but if you put inside the loop you can choose the COM Port anytime.Ĥ.5 Visa Bytes at Port goes inside while Loop. You can put VISA Configure Serial Port inside the while loop. 3)Ĥ.4 The VISA Configure Serial Port and VISA Close go outside the while loop. 2)Ĥ.3 The first two Case are for writing a string and the last one for reading. 1)Ĥ.2 Create three Case structures inside of while loop in Programming > Structures > Case Structure.

(from Arduino).Ĥ.1 Create a while loop in Programming > Structures > While Loop. Flash, Processing, MaxMSP.) The boards can be assembled by hand or purchased preassembled the open-source IDE can be downloaded for free. Arduino projects can be stand-alone, or they can communicate with software running on your computer (e.g. It's very useful for data acquisition (purpose of this tutorial), instrument control, industry automations.Īrduino is an open-source computer hardware used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other physical outputs. LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a visual programming language developed by National Instruments.

This tutorial will not explain how LM35 sensor works.

You’ll learn how to send a string and receive data available at USB port.įirst of all, C programming skills and LabVIEW diagram block knowledge will help. This instructable is a quick tutorial explaning how to connect your Arduino to LabVIEW thought USB.
