    Arduino - Points/turnout Control

    Hi Simo, glad you like this Instructable. I used Hornby R8014 points motors (not surface mount) but should operate with same voltage and current. Please check the Vcc2 power supply which must be about 15 volts and capable of supplying peak current of at least 1 amp. Do your point motors operate of the track ok i.e. in free air movement? Please check alignment and freedom of movement of lever to points. You may have to adjust the timing in the Arduino sketch. I have 150 to 250 milliseconds on time delay (250);

    Garden Train - Arduino / Wireless DCC

    Yes any other wireless comm would work as the DCC part is generated onboard the train. All you need to transmit is the instructions.You would probably have to make your own app on a phone - I do not know how Engine Driver transmits data.

    Please refer to my instructable 'Model Railway DCC Arduino wireless commands on a dead rail system' for details of the nRF24 replacement for the obsolete RF28.

  • Model Railway - DCC Command Station using Arduino:

    Yes you can control your layout by having 12v battery power in each train along with Arduino programmed to provide DCC command address bytes. The Arduino is connected to a H bridge to convert DCC signal into +- 12v supply for the installed decoder. The on-board Arduino also has a wireless receiver to accept the command address from the base station which consists of an Arduino and wireless transmitter.

  • Model Railway DCC Arduino wireless commands on a dead rail system

    I have upgraded 2 of my garden trains with the wireless DCC system. So yes I do think it was a great idea from you Martin. The old LGB loco needed a more powerful battery. I am currently using a small lead-acid 12v battery from an alarm system. It sits in a modified truck along with the Arduino circuit. This is much easier in these large scale trains of course. I agree, the Li-Po batteries are a bit scary for some. I use the Li-Ion type in my diesel engine which has space under the floor to house them.

  • Model Railway DCC wireless commands on a dead rail system

    Hi MartinYou should use the Maniacbug library driver for the nRF24Arduino driver for nRF24L01RF24: Driver for nRF24L01(+) 2.4GHz Wireless TransceiverRF24: Driver for nRF24L01(+) 2.4GHz Wireless Transceiver I shall add this detail to the InstructableTo decrease processing time, the Arduino now only accepts one loco address in line 36 (int locoAdr = 3). The use of preamble + 3 bytes or preamble + 4 bytes (depending on DCC Command station in use) must be entered into line 53 { { locoAdr, 0, 0, 0, 0, 0, 0}, 3} // enter 3 for 3 byte and 4 for 4 byteI have not been able to complete this automatically in the Arduino code as yet.Also, I have removed the printf functions and other radio functions not required and the speed is a lot better. Regards Bill

  • Model Railway DCC wireless commands on a dead rail system

    Hi Martin, I do not get this error. Have you got all the library files included for the nRF24.h and nRF24L01.h? There area few entries in the Arduino forum that cover this error code. Have you the latest Arduino IDE 1.6.12 ?The radio will not work if this line is commented out (//)By the way, what Command Station are you using ? Does it supply a 3 byte address or 4 byte ? My code is for 4 byte. I will develop code for 3 byte (or both soon). The nRF24 radio is quite slow and adds a noticeable delay to transmitted commands which might be a problem. Need to look into this further.RegardsBill

  • Model Railway DCC wireless commands on a dead rail system

    It should work:- pin 6 Arduino to 2 on mobile decoder. To get the speed packets, your code in the mobile decoder should be similar to mine as Geoffs filters out all non-function packets.I have found variations on the output of different DCC Command stations on both packet contents and voltage levels. e.g. Bachmann EZ operates from a 16 volt supply (dangerously high for some decoders!), whereas my own runs from 12volts. This will make a difference to the resistor chain (10k / 4k7) on the input to the Arduino.Good Luck and thanks again for the ideas.Bill

    Garden Train - Arduino / Wireless DCC

    Hi MartinI have found a way of using Arduino Mini Pro and nRF24 to transmit and receive DCC command station data. The on-board Arduino must run the basic clock sequence and only the packet data needs to be transmitted. I shall create another instructable soon with details.Regards

  • Model Railway - DCC Command Station using Arduino:

    I have not included a programming feature on this command station. This must be done elsewhere, for example I use 'Decoder Pro' software on my Mac along with a Sprog II USB programmer.

    Garden Train - Arduino / Wireless DCC

    Hi Martin, With limited space in HO/OO locos it will be difficult to achieve a DCC wireless solution. You will need at least 2 x 1.5v batteries plus step up voltage circuit to supply 12 volts to the H-bridge. It should be possible to transmit the DCC signal by wireless to one of the bridge inputs and reversing the signal via a transistor to the other input to provide a 20+ volt peak to peak output that follows the received data. I will purchase a nRF24 module and check it out. Will let you know how I get on.Thanks for you idea.
