    DCC Controlled (PECO) Turntable Project using a Arduino Uno

    in DCC Discussion Topics (not questions)

    Posted

    Well I've done the easy part, me thinks, but really lost with the software side, and reading the latest post, going with the A4988 version doesn't seem to be the best route, but that what I've got at the moment.   So this is what my hardware looks like so far. The gear ratio works out at 53.91:1, I think. 60T/16T and 236T/16T.  I do need some help with the sketch do I just load "DCC_Fully_Working_with_Parking_Sensor.ino" and then compile? I have attached the two libraries (DCC_Decoder_master and AccelStepper) to the arduino but not sure what to do or copy next? Also to test do I just upload the "speed_vibration_harmonics_test.ino" to run the speed tests?

     

    Any help greatly appreciated.

    I have had a fair bit of interest in the board I made.

    Pricing is as follows:

     

    Bare board - £20 Incl. P&P

    Complete kit (less Nano but including A4988) unassembled - £30 Incl. P&P

    Complete kit (less Nano but including A4988) assembled and tested- £40 Incl. P&P

     

    Comparable pricing with Uno and Adafruit shield pricing but in a neater package with a DCC interface. :)

    I have a few boards/kits left and if there is interest I will get some more in. I may start using the Micro Pro board as it has more interrupts (the Nano and UNO only have 2 I/O ports capable of interrupt!).

    It will require some minor design changes but it is possible to hook up some of the I/O to pins to enable them to be user configured.

     

    If anyone has any requests I might look at doing other DCC Arduino project PCB boards for lights or signalling?

     

    Where is the best/most convenient place to upload my AccelStepper libraries with 'setBacklash'?

     

    Regards,

    Hi, Seems like I needed to be validated first, I know this is late in the day, have just found this all, Any chance you have any bare boards available?

     

    thanks
