Respectively representing pre defined decoders with 15 Servos F0-F14 and 1 LED F16, 13 Servos F0-F12 and 4 LEDs F13-F16, 10 Servos F0-F9 and 7 LEDs F10-F16, and last 17 LEDs F0-F16 like the original decoder I presented.
The Double Blink Function Configuration 3) will alternately blink the designated pin and the pin immediately following (as for a crossing gate). If you change a configuration CV it is recommended that you either reset the Pro Mini or power cycle it after you make all your changes. If you did everything right, you can control your decoder and turn on and off 17 functions at will. Once you get it assembled and programmed, hook it up to any DCC track bus and power supply, and away you go! This would enable  you to use the servo to throw a turnout, power the frog, and indicate the position of throw. Likewise, a fascia switch could be used to control turnout position, but it would also use another pin per servo (now 3 per servo) so a total of 5 servos could be supported. This all started in August of 2014 with a nice, simple idea in a blog post to control animations in process. Additional note: If you ever intend to use a servo motor attached to pin 13 -- the same pin used to drive the built-in LED -- please unsolder the LED, or the LED dropping resistor on board, or cut the trace to the LED to disable it.
Please note some programming cables sold have scrambled pin outs, and color coding is wrong!
Build the decoder hardware variant of you want, and then look here for information on setting up and loading the decoder sketch (program) of your choosing. In the original effort, I pointed out that I am not a proponent of asking modelers to learn how to program-- just learn how to use these new tools. Configurable accessory decoder where servo timing is turned off (detached) after the end of the servo transit. Accessory decoder with each function pin generating a configurable timed pulse with turn-on of the function (0 to 1 transition). Included below is a brief description of one detailed working example for a 7 servo 10 LED configuration that may help people configure their own versions for their particular modeling needs. There has never been any intention to create a competitive commercial decoder—and there still is none. You should consider making this a clinic to be be presented at the NMRA National in Indianapolis this coming summer. I encourage every modeler, regardless of hobby interest, to check out your web connections.
If I ever get to your beautiful country, I will have a bunch of these in my pocket for you!
It gave me a chance to see close up and in more detail in how you installed the components and achieved the end result.
Having the models made the clinic unique and a nice change from the standard PowerPoint presentation. I will admit you were on a clinic marathon in Portland with Animation, Lights, Sound and Cranes. Figurer Controlled model school using Rocrail Featured with northward scale DD51 and EF63 Rocrail cover for this. This is my next version of a 17 Channel Multifunction DCC Decoder based on a low cost $2.56 Arduino Pro Mini.
The BIG change is the program and library modified for the job, which I make available for modeler use. The control signal is directly connected to the Arduino Pro Mini Pins labeled 3-13 and A0-A5.
The green LEDs used as Function indicators are especially bright even with very low current.
To get the LEDs to fit side by side on .1inch centers, I used a sanding disk mounted in a moto tool to sand the sides down just a bit in parallel with the LED pins. This will set up all the default CV’s and then permit you to modify them with your DCC controller of choice.
You will note that as the decoder powers on, it will run through a test cycle turning all functions on, then all functions off—and only once. With a little more work than just copying and editing you can build complex functions beyond what is presented here.


Obviously it would use anther pin (of the 17 available) per servo, so it would be limited to controlling 8 servos.
But it would seem to me that the fascia switch would substitute for DCC control, so only the endpoints and throw rates would use the DCC interface.
In fact, I very much hope this will spur more modelers on of all interests to try these out. There are two new boards to help construction: one with a 100ma voltage regulator and one with a 1 Amp regulator. OSHPark offers a public service fabricating very high quality, low cost PC boards in low quantities.
I cannot guarantee pulse and servo timing consistency if these functions are used simultaneously. Delete your previous version and replace it with the new NMRADcc folder into …\My Documents \Arduino\libraries folder. Before changing the CV settings take a look at the initial settings and make small changes first to observe the effects. If I do, it may not be another 8 clinics, though -- that was a great deal of prep and effort.
Call into question I have spent quite a bit of money on my DCC layout only to discover that Computer Control via my PC would represent the next logical step for 1 would.
After many hours spent trying different layouts and nerve-wracking to fit exemplar railroad track plans into a restricted place it dawns on most tocopherol. Assembly is pretty straightforward if you’ve ever soldered a small set of components before. They are plugged into an IC socket cut and soldered to the board-- it keeps them in somewhat neat order.
Special programming was added so starting up many servos would not cause a major current surge for the power supply. I had considered another option to pair a second relay control pin as another configurable function, but have no immediate need myself. Since some of these are not what I would use these for (animation being in my foremost thinking), let me know via this forum, what might be worthwhile, and as time and interest permits, I might be able to make these available for modeler use! I have no vested interest in this, I just love to see people get enthusiastic in what they do. The Decoder3P is configured to accept a larger package component like a L7805 (1.5 Amp) regulator. All aspects of their design and construction are available for public use with no restrictions. Remember, you can configure  each pin to do to what function you would like, including a 17 servo driver. This should give modelers a starting point, and a better understanding for customizing their decoders. Undoubtedly now, there will be more of these to come, more variations, more learning, and more improvements.
This will reset everything including the decoder address, when the pushbutton on the Pro Mini is pushed (reset) or by powering the decoder off then on. With the model in front of me I can study both before and after the clinic, giving me many more details and insights. And you would drastically reduce the number of show and tell items that you would have to transport. One freight Model train locomotives are built today with type A computer chip off to curb the lights Computer controlled model trains are today the standard to be found Hoosier State Building a model rail layout model train computer control. This is the first psychometric test run of my 85 completed model train layout with computer control system. Yes, that does mean it can support 17 servos, each with rate, start point, and end point setting via DCC CV’s, per pin, as well as new LED configurable functions.
You could also use a solderless breadboard (like Radio Shack 276-003) to assemble a decoder. If you control a Servo with a particular function pin, I recommend that you remove the LED at that pin.
You are prompted to think beyond turnout control, but please realize that I don't want to spend all my modeling time doing updates for these.


However, there are no speed tables, jump starts, momentum effects, back emf, do-dads, whizzies, or anything else but a direct mapping from the 0-127 speed setting to the motor Pulse-Width-Modulation plus direction control of the selected motor. These are manufactured and distributed by many companies worldwide, some for as little as $2 (quantity one) including shipping! I am not trying to do that here, merely trying to show others that these little guys can add a great deal to your modeling enjoyment. I hope those modelers reading this can take advantage of the effort, and share your variations with others.
You will know when the default CV setting are being reset as the decoder will flash Digital Pin 14 (A0) for one second. We deficiency it to personify usable to atomic number 33 many people as possible so we’re building it inwards Java to run model train computer control.
Regardless, you should cut off the surface mount LED Pin 13 indicator or its dropping resistor on the Pro Mini Board, as it is both redundant and may interfere with the function assigned to that pin. The on-board power supply, which powers the board from the DCC bus directly, can also be dropped. Depending on your application, you might want to use the smaller package to fit in a smaller volume if you don’t need the power. If you have a voltmeter, plug your cable into your computer, but not into the Arduino Pro Mini and measure the voltage from the black wire to red wire-- it should be +5 volts. With such a cheap and powerful tool, a series of tested, working, and packaged instructions (called Sketches or programs) to set up these versatile DCC decoders with many practical functions are made available. Please note, time dependent functions like servo control and motor speed control will interact. The multifunction decoder address can be changed to another short DCC address by changing CV 1.
Arenaceous has terminated 230 feet of track entirely controlled exploitation his rest home computer. On the Arduino Pro Mini these are labeled 3-13 and A0-A5 and they directly correspond to standard DCC Decoder Functions F0 through F16. This new supply can also power decoder logic, so this will minimize the load on the DCC lines. This allows for a higher power, local 5 volt power source from batteries, power adapters, and other power supplies. This is not a commercial product, but I dare say there are hundreds, maybe thousands of these that are in use by modelers around the world-- judging from the feedback.
I doubt very much that I would have pursued all these variations, especially the accessory decoder variants, without the interest and enthusiasm shown by scores of modelers, literally, from around the world.
This new board attaches to the Arduino Pro Mini board directly, via header connectors, pins and sockets, or plain wire. If you power the little board(s) with an external 5 volt supply or batteries, omit B1, C3, and IC1.
I have tested servo operation simultaneous with motor speed control and it worked, but motor timing was affected.
The value of C1 is listed at 22uf, but I use whatever the largest capacitor I have on hand and can fit in the space with a 25-35 volt rating. With an external 5 volt source, if you intend to drive the motor(s) you can only omit B1, as the DCC signal is rectified and used as motor power through the H-Bridge. I am using this with small motors (50ma drive) in situations where such timing is not at all critical.
They are available in many hobby stroes, and can be ordered direct from Chinese manufacturers through ebay at a steep discount. The 1N4148 diode can be almost any small signal diode with a 30 volt or more reverse voltage specification. If you do not intend to power any motor(s) you can omit the SN754410, as well as C6 and C7. Note: while cheap servos are available, their noticeable characteristic is a great variability from servo to servo, including swing measure, noise, and current draw.
