Uploaded from my 1.4 project that interfaces with the Lego WeDO. Control speeds by entering 1,2 or 3. Reverse direction by using r and stop by entering space bar. The cat size changes based on distance sensor.
Project created in 1.4 to use Lego WeDo motor blocks to create a small fan, with different motor speeds. Extend for upper grades with virtual fan, more controls, use of gears etc.
