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.
