So I know that you need a Usb cable to the brain but i click on the " Build" option but it doesnt appear on the brain
what do i need to do? the two option (the controller and the brain) are the color gray instead of green how do I fix this
Make sure your brain is turned on, try unplugging and plugging back in, try a different computer port, switch USB cables, and try a different brain or laptop (in that order).
