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.
