Dear Electro Tech,
I am very new to electronics so please bear with me.
I am TRYING to use an Arduino prototyping platform to operate a linear actuator.
(http://arduino.cc)
I bought 1 Unipolar Linear Actuator
Digikey.com item # 403-1030-ND **broken link removed**
and 1 unipolar stepper motor
Digikey item # 403-1001-ND
**broken link removed**
Both motors have 6 wires.
THEN I found this tutorial on the Arduino website **broken link removed**
So I bought a ULN2003A driver (because thats what the arduino tutorial used), thinking that I would be able to run my motor with it. BUT the motor in the tutorial has 5 wires instead of 6 and uses a potentiometer, which I do not want to use.
I could not get either motor to work when I hooked up the ULN2003A.
The funny thing was, I hooked my motor directly to my arduino board and it worked....but the arduino ATMEGA168-20PU chip got warm so I think that cant be right either...it didnt get HOT though.
So anyway, my question for you is....How can I run my motor safely and what Driver should I use with either of the 2 motors that I have already purchased?
Do I even NEED the driver?
Is it ok if the Arduino gets warm but not hot?
Thank you so much for your time!
