Hello all- Thanks in advance for reading. I am attempting to build an automated candy machine for Halloween with a Servocity Linear Actuator with Feedback Model HDA 12-2
I do not need the Feedback function for this project, but I cannot seem to make the linear actuator work without it.
When I apply straight 12v power to the red and black wire, it extends, and reversing the polarity brings it back. For the project- I was planning on having the Arduino Uno turn the 12v dual optocoupler relay on for
3 seconds- dispense the candy from the container, and then reverse and close.
So I don't need the feedback, but all of my wiring attempts are not working seemingly without the feedback wires attached. The problem with the following diagram that I have been using is that it references a RobotGeek Sensor Shield, which does not exist anymore, so I cannot tell where the feedback wires would go. Here is the link to the wiring diagram I am following:
Red and Black wires are to the common parts of the relay, and I put Blue to Analog 0- but where would yellow potentiometer reference and white potentiometer reference go to on an Arduino Uno? Do I need a motor driver or H bridge? Remember that I do not need the feedback- can you think of anyway to bypass that function. Thanks as always for your time.
