This post looks at extending the idea to using the accelerometer to pick up directions and send them to the robot unicorn (that still seems weird to write). Microbit's accelerometers, using the x and y directions, provide the inputs and then send the direction commands. The robot unicorn code is the same in the second post, the new code for the gestures is shown below.
This a work in progress it detects x and y changes together so it does have a tendency to do one direction and then the other. This needs further work.
