Pushing Meowbit to determine quantity of hardware it can handle

Video, adding more hardware and animation of sprites to determine how many pieces of hardware Meowbit in Arcade can handle. We have found that a maximum of 7 animation elements can be called before 021 error code appears when we are also running 4 motors at different speeds and directions. In this video we show that it appears that neopixel (array of 8), single LED, DC motor, animation of one (of 2) sprites and 4 DC (yellow TT) motors can be run without 021 error.
