This instructable is a quick tutorial explaning how to connect your Arduino to LabVIEW thought USB.

You’ll learn how to send a string and receive data available at USB port.

First of all, C programming skills and LabVIEW diagram block knowledge will help.

You will need:

• Arduino UNO;
• LM35 (Or other sensor);
• LabVIEW Software with NI-VISA Driver;

This tutorial will not explain how LM35 sensor works. See its datasheet.

What's LabVIEW?

LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a visual programming language developed by National Instruments. It's very useful for data acquisition (purpose of this tutorial), instrument control, industry automations.

Arduino?

Arduino 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.
Arduino projects can be stand-alone, or they can communicate with software running on your computer (e.g. Flash, Processing, MaxMSP.) The boards can be assembled by hand or purchased preassembled; the open-source IDE can be downloaded for free. (from Arduino).
