Title: stepper motor + beam sensor
Post by: dsesmg on December 15, 2008, 12:39:47 AM

Hi, I used arduino before to control a stepper motor by using ULN2003 circuit(http://electronics-diy.com/electronics/stepper_motors.php) as the driver of my stepper motor.
I am trying to build a small conveyor (Length : 300mm x Width : 130mm), which rotates for a designated distance(for about 100mm) every time a beam sensor is disturbed.
So, I figured that this kind of simple process can be done by other controllers that are way cheaper than arduino.
My question is (1) what type of software and chip should I use for my application?
(2) In order to use a beam sensor with this stepper motor driver circuit(http://electronics-diy.com/electronics/stepper_motors.php), how should I connect the sensor to this circuit(or to controller circuit)?

My stepper motor has a specification like this.
*Voltage    *Current    *Resistance   *Inductance   *Holding torque
 4.0V          0.95A         4.2Ohm          3.3mH          1.6kgf.cm

Any word of advice from you would be very helpful to me.
Thank you.

You can't get much cheaper than an Arduino . . .
