Hi Roy,

this is the site where I bought the optical sensor YxRobot:

http://www.plexishop.it/en/arduino/sensori-per-arduino/angular-position-transducer-optical-encoder.html

Its cost was about 5 Euro incl. tax.

It is an Italian shop-website.

Hello Roy.
Here are pictures of the sensor YwRobot used by me and my trial version of your turntable project.
Tomorrow I will receive two "hall effect sensor", so I can check which of the two systems for detecting the zero point seems more accurate.
Greetings.

Hi Roy.

Tomorrow evening I take a picture of the prototype.
For now I can tell you that the optical sensor is a YwRobot.

Ray, I have to give you some good news: I've made for your test project.

I just replaced the Hall Effect Sensor (RS370-6896) with an infrared optical sensor that I bought long ago on e-Bay.

The magnet has been replaced by a thin object that with the rotation of the bridge goes to interpose the sensor fork.

I did not even have to change your sketch!.

It all works very well, for the time being commanded by Intellibox from Uhlenbrock (first version).
 MANY THANKS FOR THE HELP!!!!!!

You did not think even you add a seven segment display to signal the position?

Good giornagiorno. First of all, thanks to everyone for the effort put in the projects presented in this tread!  
In particular, Ray, I tried to implement your project, but loading the sketch in ArduinoUNO me the following error is reported:

  sketch_feb07b.cpp.o: In function `__static_initialization_and_destruction_0':
C:\Programmi\Arduino_1.0.5/sketch_feb07b.ino:50: undefined reference to `AccelStepper::AccelStepper(void (*)(), void (*)())'

Someone is able to suggest a solution?  

Thank you very much & greetings.  Rovilazz

Hello Mr. Tender.
I have recently discovered this forum and I'm curious about your project.

I have to make a small turntable (for DCC) in HOm scale reproduction of a small Italian station, which no longer exists in reality.
Your project would be just perfect for me !.
I have already procured the Adafruit Motor Shield v.2
When you manage to complete the 7 part of your good project?.
Big thumbs up from me for your idea.
Greetings.
(sorry for my english ...)
