Linak LA12 and Arduino

Hi!

I've got motor called Linak LA12), and I was wondering if it is possible Arduino to detect its position. I am newbie and I believe I don't understand technical thing from user manual well enough to get this work.

What I've tried so far is to put straight 12V to motor and then monitor other pins with AnalogRead to see if they change. :grin:.

That PDF seems to cover a few different variations of the actuator. Can you give details of the exact model you have.

One variant seems to include a potentiometer to report the position - but it may produce an output of 10v which would damage an Arduino.

Exact model number is 121P00-11002420, so it's the same on page 12

You will need to measure the output voltage from the potentiometer. My guess is that it can be over 5v and, if so you must use a voltage divider to ENSURE the Arduino analog pin NEVER sees more than 5v or less than 0v.

I presume you are planning to control the motor power with your Arduino? What do you plan to have between the Arduino and the motor? (eg. a h-bridge driver or relays).
