The LEGO WeDo robotic set (Produce Number 9580) has 2 sensors, a
tilt sensor and a distance sensor (often described as a motion sensor).
Let's do some experiment with the
distance sensor. Connect distance sensor to the hub, connect hub to computer USB port, Open Wedo software to add program, add a START button, add a "Numeric screen output", add a motion sensor as input to the "Numeric screen output", add a loop to repeat (see
photo).
See photo of the
experiment setup. The experiment showed that the output value of the distance sensor changes from 0 when it is far away to 10 when it is nearest to the sensor. See
video.
