Turtle Oscilloscope

For the experimental Turtle Art Portfolio V18 for the XO hardware, this program uses the programmable brick and sensor input . (As at V19 Turtle Art Portfolio, the 2 imports below are no longer required.) (As at V44 of Turtle Art, the programmable block is supported but sensor input still is not.)
