Controlling relay using Arduino and Labview

The above fritzing uses a 5v relay , If you are using a 12v relay you need to connect an external supply for powering the relay.

This is the simple relay control operation, where the control can be feed to the arduino by using Labview frontpanel, This example uses 3 DC motor to represent switching ON and OFF of motor, this same program can be used to control many application for switching and a timer can be added for controlling timed control applications. The above circuit can be modified for the controlling of AC circuits too, be cautious when connecting with AC circuit, use AC circuit only when needed.

Labview VI can be downloaded from here :
