Hi Karan, you can turn this VI into a "subVI". Go to your front-panel, and right-click on the icon in the top-right hand corner, and select "Show Connector". You can now connect those little boxes (terminals) to your controls and indicators. Click a terminal, click a control/indicator. Once you've done all that, right-click on the connector pane, and select "Show Icon". You can modify the icon, too. Drag it and drop it into your main VI, and you can use it as a "single block".
