The EV3 Control Center is installed with the leJOS SDK on your development PC. The Control Center is a powerful tool that allows you to view and control many aspects of the EV3 controller. With the EV3 connected to your PC, you can start the Control Center from the leJOS pull down menu on the Eclipse tool bar. You can also start Control Center by clicking on this file:

C:\Program Files\leJOS EV3\bin\ev3control.bat

You might want to create a desktop shortcut for that file as you will probably use Control Center often.

Control Center allows you to see the programs and files present on the EV3, allows you see the console (and keeps a record of what is displayed), allows you to remotely push the buttons on the EV3, start and stop programs, look at sensor values and control motors. In short, the Control Center is a very powerful and useful utility to get familiar with.

With your EV3 connected to your development PC, start Control Center. In the name box you can type the name you assigned to your EV3 and click connect, or you click search to have Control Center find your EV3 for you. If connected over WiFi, you will need to put the IP address of your EV3 (visible on the EV3 LCD) in the name box and click connect.

Note that the Control Center has a few quirks. If the connect to an EV3 fails, there is no error message. The Connect button will change back to the unpressed state and that is all that happens. At the same time, when the connect is successful, the Control Center may not give any indication that it has connected. You will need to click on one of the tabs to see if data displays.

Start the Control Center and connect to your EV3 and take some time to explore what Control Center offers.
