Circuit playground to arduino uno, is it possible?

After finally getting the motors of my chassis to work, they only seem to work with the uno board. I need the circuit playground neopixels as the app created moves the motors (attached to uno) and changes the neopixels on the circuit playground. My lecturer suggested connecting them, however I don't know how to or if i could get the motors to work with the circuit playground i'd do that but that doesn't seem to work at all.
