Much cleaner than before  :thumbsup: Looks like it might ending looking factory  ;)

That is what I'm talking about  :thumbsup:. This plus actuator = sex when its done

I'm none too pleased.  I should have looked more at the dimensions.  There's no chance that it'll fit in my dashboard.  This project is sure going to hell in a handbasket.

I'm going to try a new approach.  I'm not scrapping the motorized idea but I may end up scrapping the actuator if I can't get it to fit in exchange for a servo.  More time and more money, but I am learning a lot from this endeavor.  Wonder what I could use a linear actuator for if not this project...

That really sucks man.  Have you ever seen the after market power window motors?  Ya know, the ones that look like a wiper motor but there's a loop of cable that turns a "flat gear" looking thing.  I've used those in the past with good results.  You can be a little more creative in mounting the motor, and they give pretty good torque.  Just a thought.

Well I got the servo today but I can't use it yet because my controller hasn't arrived.  I may try to figure out how to mount it first as I'm 95% sure that this will have more than enough power to move the screen up/down.

Other bad news came as well though.  I killed my ITX motherboard with a BIOS update.  It's getting replaced but I have to wait for it to get to CA then wait for a new one to come back.  Since I have no screen to display anything on I'm not really too upset.

The project will plow on.  Estimated time of completion: hopefully before the end of the universe.  I just want something that mostly works at this point.

Got my Arduino today.  Of course I couldn't wait so I went and tried to see what I could do.  Whipped up a quick program and hooked everything up; here is the result.  I only wonder if the servo will have the power necessary to make the screen rotate.  It shouldn't be too much force, but I won't know for sure till I try.

* EDIT *

In my own hacked up way I managed to test it with a paperclip and some glue.  It can move the screen upwards.  Down is easy so I didn't care.

* EDIT 2 *

I was just driving the Arduino and such off of USB power as can be seen in the video.  I decided to get a 9V battery a try just to make sure it worked fine off of USB.  The servo actually has some serious power once you hook it up to a higher amperage power source.  I'll have no problems at all with this servo moving the screen.

* EDIT 3 *

I absolutely couldn't wait to have test it actually moving the screen.  Here's a video of the movement in action.  I need to put a bigger arm on the servo to get it to swing the screen more, but this is exactly what I was looking for.

what happens when you press the button again mid-motion, or if you pressed and held it?

To answer your two questions:
1) It will change direction
2) A press is only counted once no matter how long you hold it

Code: [Select]
 buttonState = digitalRead(buttonPin);
  if(buttonState==HIGH) { // Button is down (5V input)
    Serial.println("HIGH");
    if(lastButtonState != HIGH) {
      // Change direction if the button was last up
      servoPosition = (servoPosition == 0) ? 179 : 0;
      lastButtonState = HIGH;
    }
  } else { // Button is up (0V input)
    Serial.println("LOW");
    lastButtonState = LOW;
  }
  Serial.println(servoPosition);
  myservo.write(servoPosition);
  delay(15); // Allow the servo time to respond (15ms)

The Arduino is coded very similar to C, that's why this was so easy for me to do.  The main difference is that it really only has two functions: setup() and loop().  Setup is like an init function and loop loops.  The above code is from the loop.
