Example code

Try the example Joystick sketchpad right in your browser in Eduingo AI Lab. Use the joystick to move a yellow dot around the matrix, leaving a trail behind it, just like on a drawing board. Press the joystick to clear the picture. The variables x and y tell where the dot is, and the function that guards the edges keeps the dot inside the matrix. Try drawing a little house.
