Today I experimented with making a drawing machine using a Lego WeDo 2.0, Scratch 2.0, and a marker. The Learning Technologies Center has been making Lego Drawing Machines for years, but the bluetooth WeDos allow for the use of two motors that you can turn on and off to make interesting patterns. Click through the slideshow to see the car, the programs controlling it, and the drawings I made with it.
