Simon-

 

Take a look at my earlier posts or on page 7- luce001 posted some nice modifications to my code for a 4 track table with release.  He also added an OLED LED display, but you could just comment out that code if you don't want it.  It is a rather nice solution.  Haven't read this thread in a while.  fun to see what people have done with it.  I am really happy with mine.  Made two tables to date, looking to make two more drives for the local club.  I will post my updated code using some simpler drive modules once I build rev 2.  Best of luck.

 

Talk soon

Hi Eric, I have now downloaded the sketch from luce001 and it works fine, but I'm having problems with the u8glib file. There doesn't seem to be one available as it is no longer supported. Is there a sketch with the newer u8g2 file in that you know of please?

Simon

Hi Eric, I used everything that was suggested on the 1st page of this link, plus a DCC interface from Ian Jeffery.  I am using the hall effect sensor and the Adafruit driver. I went through all 27 pages of the thread yesterday, but failed to find the sketch that I needed, so I was hoping someone might have it. I did come across the 7 road sketch, but I don't think this cut the power to the motor. My turntable will be infrequently used, so I don't want the  continuous whine.

Cheers, Simon

1. Hi. I've just returned to this thread because my turntable and Arduino have stopped working. They haven't been used for a long time, and seem to have lost the programming, so I stripped out the turntable and brought it back into the house so I can go back to square one. The other problem was that my PC crashed last year, and I've lost all the information. What I'm after is the sketch for a 4 road turntable with the power being turned off from the motor please?

Simon

Just to say a big thank you to the great help from Ian Jeffery and along with the posts and sketches from Ian and Tender, I now have a fully functioning Peco turntable using all the hardware as described on the first page of this extremely long thread, which I only discovered recently. My T/T stops at 4 different roads, and the motor powers down each time, leading to a nice quiet life!

Thanks guys.

Hi Simon,

 

Would it help if i sent you my sketch as well to get you going ?

 

Ian.

Yes please Ian.

Hi Simon, no the hardware is the same.  Some others have used a different Stepper Driver to the Adafruit Motor Shield but that will require a modified Arduino Sketch to my original postings. You might note that post 512 has an updated sketch which removes power from the stepper after reaching it's position but that only works for a 180 single road turntable. I'll update the 4 road sketch and post here shortly.

 

Keep us posted on your progress.

 

Ray.

Hi Ray, I've just connected everything up, uploaded the sketch and it all seems to work very well, although I might have a little bit of unwanted friction that I need to address. As I'm still getting to grips with understanding the sketches, could you possibly post a copy of the 4 road sketch please?

Cheers, Simon

The DCC interface works a treat. Highly recommended.

I have just bought Ian's DCC interface, and it works really well. No messing about with components and soldering etc.. Great little item. Check out his webpage DCCinterface.

Hi Ray, Don't know what happened then! Thanks for letting me know about the hardware. Started buying off eBay and RS for the bits. Downloaded Arduino software. Looking forward to getting to grips with the programming!

 

Cheers, Simon

Hi. I now have all the hardware except the Hall sensor which is due next week. Only other question I have is which 9v power supply would you recommend?

Cheers, Simon

Hi, did you ever design a circuit board from the post #8?

Cheers, Simon

Here is a pic of the finished board - with screw terminal headers soldered on.

 

 

 

 

I'm currently in beta testing with them, and also setting up an online shop.

 

what do you think ?

Board looks great. It goes directly from the DCC bus to the Arduino then?

Cheers, Simon

Hi Ray,

I've just discovered this thread, and I was wondering whether there was a hardware update from the original post. I've only just started to build my railway, and have a Peco LK-55 turntable, and this all sounds ideal for my purposes. I will be having 4 roads under DCC control.

Cheers, Simon
