Arduino Mood Cue

Chief and I did another Arduino project today. Since it was raining today, we traded our bike ride for a tech ride. Today we learned about potentiometer and stepper motors. Nice code! Twist the potentiometer to control the indicator arrow on your mood: Stay Out — Knock Please — Come In.

The project book added capacitors to even out the voltage load on the stepper motor and the potentiometer.
