Overview
This zip file provides a comprehensive tool for integrating an Arduino-based distance measuring system with LabVIEW. The project showcases how to use multiple ultrasonic sensors connected to an Arduino to measure distances in real-time, interfacing seamlessly with LabVIEW for data acquisition and monitoring. This project is designed for educational purposes and serves as a practical example of building a DAQ-like interface using LabVIEW and Arduino.
Features
- Arduino-LabVIEW Integration: Seamlessly interface between Arduino and LabVIEW using serial communication, enabling real-time data acquisition and control.
- Multiple Sensor Support: Easily configure and measure distances using multiple ultrasonic sensors connected to an Arduino, simulating parallel measurement.
- State Machine Structure: The Arduino code employs a robust state machine design that follows the "open-configure-run-close" structure typical of LabVIEW applications, ensuring smooth operation and easy control.
- Dynamic Configuration: Adjust measurement delays and start/stop measurements directly from LabVIEW, providing flexibility and control over the measurement process.
- Real-Time Data Visualization: Use LabVIEW to visualize the distance measurements in real-time, making it easy to monitor changes and analyze data.
Dependencies
- Arduino IDE - Required to upload the firmware to the Arduino microcontroller.
- LabVIEW by National Instruments - Platform for developing and running virtual instruments and acquiring data from the Arduino.
- NI VISA - Necessary for serial communication between LabVIEW and the Arduino.
