Project Idea Vol.2

-Air Screen -

Servo Motor can't work infinitely, so I got Bipolar Stepper Motor today.

Midterm Goal:
Assign the movements to this Bipolar Stepper Motor. Put the colored line on the fan with the motor. Check possibility to be seen colored ripple ring or some colored pattern in the air afterwards.

Final Goal:
Put the sensor into this. It can interrupt its movement by the person passing by in front of this sensor. Make this as 1 unit and consider to expand this installation by using different color.
