1) Make sure your board is plugged in snugly and the USB cable is turned around correctly. You should see a steady green light on your board.
2) Try a different USB port on your computer. If that fixes it, it doesn't mean the first USB port is broken, it may just be that your board didn't establish a connection with your computer the first time.
3) The drop-down menu* at the top of the code editor should say 'LSC Board' for Windows and Mac and something like /dev.tty.... on Chromebook. If it says something else, click the drop-down and select a different option.
*Depending on which version of our software you are using, you may not have a drop-down menu on your code editor.
4) Unplug other USB devices from your computer to ensure nothing is interfering with the connection.
5) If this is your very first time using your kit, you may need to restart your computer after installing the software.
