Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit

Post by LAser »

Hello,
Can you help me?
I need two electric motors that I can connect with LabVIEW and Arduino. The motor is going to control a mirror (http://www.thorlabs.com/thorProduct.cfm ... mber=KM100).
This mirror is used in the laser technology. The mirror reflects a laser into a fiber. At the end of the fiber is a photo-diode which measure the light density. The photo-diode is connected with an Arduino UNO board. If the density is not enough the motors have to move the mirror in the right position. The usually used motor is:

It should be similar as possible. Thank you.

The motor specifications do not mention current draw, but given the high gear reduction and relatively short travel, it should be well within the capabilities of the motor shield.

Controlling the motors is only half the problem though. For full control you will need to read the encoder feedback. Are you planning to do this with the Arduino too?

Thank you very much for your fast answer. Yes, I like to do it with an Arduino. Which one (UNO, mega, Leonardo, …) would be the best to for me?
Should I use a Step-motor or a Servo-motor or another one and with which shield will it work? Which of your products do you suggest to me?

The photo-diode sends a voltage back so I have to use this signal to move the motor in the right position.

Either an Uno or Leonardo will work with the V2 motor shield, and should have enough pins to read the encoders also. The motors you linked appear to be regular DC motors (not steppers). The encoders will allow you to track the rotation. You will need 2 pins for each encoder. It looks like these motors also have limit indicators. These will require another 2 pins per motor.

So it is possible to connect this motor (http://www.thorlabs.com/Thorcat/17600/Z812-Manual.pdf) with this shield (http://www.adafruit.com/products/1438)?

Yes. But you will need to make an adapter for the motor cable. The Motor+ and Motor- pins will connect to one of the motor terminal blocks (M1, M2, M3 or M4). It looks like it also need 5v for the encoders and limit switches. The best way to make the connections for those signals would be with a Wing Shield stacked under the Motor Shield. http://www.adafruit.com/products/196

Which Pin at the DB-15 connector is the control lead Pin?

I bought your Arduino UNO and the Analog Feedback Servo. This servo has a control lead. Now I want to connect the Ardunio UNO with the Z812 and I don't know which Pin of the Z812 cable I have to connect with the Pin 9.

That motor is not the same as an analog feedback servo. It does not have a 'control' pin. It has 2 pins for channel A and B of the quadrature encoder. As I mentioned earlier, you will need 2 pins to read the encoder. This tutorial explains how to do that: http://playground.arduino.cc/Main/RotaryEncoders

Hello. Is it possible to combine the operation of this shield (http://www.adafruit.com/products/789) with thorlabs motorized stage (http://www.thorlabs.com/newgrouppage9.c ... up_id=3002)? Thank you in advance for a reply.

That is an RFID shield. Did you mean this one? http://www.adafruit.com/products/1438

The Motor shield V2 can drive the motors, but you will also need to interface to the hall-effect encoder signals for the positional feedback. This should be possible to do, but it will probably not be able to drive it at the same speeds as the dedicated controller.

How did you get LabView to interface with Arduino and the v2 Adafruit Motor Shield? I'm currently having problems with this, I get a 5005 error when I try to run an example VI designed for a stepper motor and EasyDriver motor shield. I tried everything here (http://digital.ni.com/public.nsf/allkb/ ... 85005981E1) and still can't seem to get the VI to actually do anything.
