Draw on the go with a small Arduino-powered CNC robot!

Well, technically, ON a box.

The wiring is really simple.  A small breadboard is used connect Arduino pins 10, 11, 12, power and ground to the three servos.  The keypad is wired directly to pins 2 – 8 on the Arduino.  That’s it.

Wait… that’s all there is to it?!?

Of course, it doesn’t work.  Yet.  🙂
