SCRIBBL3 PAD is just like the popular Etch-A-Sketch toy! With SCRIBBL3 PAD, you can escape boredom by "drawing" using the two motor knobs. Well, it'll actually be more like scribbles, but hey-it is fun! The left knob controls up + down, and the right knob controls left + right. Instead of attaching gears to the two large motors as originally planned, I used the large tires for a "grippy" feeling. When you want to erase what you've drawn, you don't have to restart the program! Just press the Enter button on the EV3 Brick, and the lines disappear! I give credit to piett71 for his Etch a sketch program; thank you! The video shows the drawing and erasing properties of SCRIBBL3 PAD. P.S. I just got new Energizer Ultimate Lithium batteries, so this is a lightweight etch-a-sketch!
