Motion Sensor

The Motion Sensor sample project implements a motion sensor on the NI myRIO. This sample project uses the onboard accelerometer to detect motion and displays the amplitude using the LEDs on the NI myRIO.

System Requirements

Development System

• LabVIEW Full or Professional Development System
• LabVIEW myRIO Toolkit
• LabVIEW Real-Time Module

Hardware

• NI myRIO

Overview

This sample project uses a Flat Sequence structure that executes the following three frames from left to right:

1. Initialize—Initializes a Boolean array that represents the four onboard LEDs.
2. Acquire and process data—Acquires the motion signal from the onboard accelerometer and turns on onboard LEDs to display the amplitude. The While Loop repeats the code until you click Stop or an error occurs.
3. Close—Resets the hardware output values to zero before the application exits.

Running This Sample Project

Complete the following steps to run this sample project:

1. In the Project Explorer window, open and run Main.vi.
2. Observe the LED Status indicator for the amplitude of the motion signal from the onboard accelerometer.
3. Click Stop to stop the application.
