Arduino Chassis for Drawing Robot modified for ULN2003 Stepper Driver Boards
thingiverse
I made a minor modification to the chassis to add standoff's so I could mount the little driver boards that came with the stepper motors. They have blinky lights and if movies have taught me anything about robots it's that they need blinky lights. Update: Added MyDrawTest.ino arduino sketch that draws a star using the AccelStepper Library Video of bot in action Updated Arduino Library with easy to use functions including penDown, penUp, moveForward, moveBackward, turnLeft, turnRight, turnTo, moveTo, drawChar, writeText and more. If C and C++ is not your thing try Tiny Basic Plus ClassBot Edition.
