Labs:

Work on this week's assignment. Make sure all planning and 3D design for final projects has been completed.

Assignment:

Build a simple machine using at least a stepper motor. Demonstrate the ability to command the machine to get repeatable results. Feel free to use other items in the lab (e.g. string, magnets, wires). How can you calibrate motor position (i.e. guarantee the "home" position is the same each time you power on the device)?
