Topic: Any Idea on what motor I could use? (for halloween decoration) (Read 113 times) previous topic - next topic

Hey all, I'm new here in the Arduino community. Recently I got an Arduino RE (specifically ARDUINO UNO R3 [A000066]). I was planning on making a halloween decoration that would turn it's head towards someone. I've been using an Ultra sonic sensor to see people (instead of a camera) & I was wondering what  I could use as a motor to move the head. 

I had thought of using a reindeer motor

Anyone have any ideas? (Like I said I'm new & tried to avoid using links)

Unless you need the head to turn more than 180 degrees a servo would probably be better than whatever "a reindeer motor" is.

The motor you show should work great, the head will go around and around and around assuming that is what you want ...

The advantage of a servo is that it always "knows" where it is pointing. They also contain all of the control electronics. With any other type of motor you will need extra hardware to determine where it is pointing and you will need a suitable motor driver between the Arduino and the motor.

Standard servos move through an arc of about 140° to 180° (varies with the model). You can get some that can rotate nearly 360° and still have position control but BEWARE that most things called 360° servos are continuous rotation servos which do not have position control. You can also get sail-winch servos that can turn 3 to 6 rotations with position control.

Two or three hours spent thinking and reading documentation solves most programming problems.

A mains synchronous motor definitely isn't what you want, thats for sure.  How heavy / big is the thing
you are wanting to turn?  You'll need to assess the required torque before choosing a motor of whatever
sort.

Skull, Arduino, a little pvc so probably around 5lbs.
