--- Quote from: HiSmartAlarms on August 05, 2019, 02:34:23 am ---Basically my plan is to put an arduino nano in the shell of the locomotive and another arduino as a controller thats at the operating position or made into a handle or something. But thank you for all the help. And until i get the knowledge and supplies I will be taking a break from this project for a while, unless something unbelievably ground breaking happens. --- End quote --- Physically, you will never get an Arduino Nano and the necessary motor driver circuitry inside a HO locomotive or even an O-gauge (Lionel) locomotive. At best, you might be able to fit it into a tender if doing steam or a box car if doing diesel. Even the small DCC modules barely fit inside a locomotive. Most locomotives available today are DCC Ready (needing a DCC module) or are fully DCC out of the box. You would be better off trying the DCC++ Arduino project I mentioned earlier or going fully DC and setting up track blocks. In which case you would generate the power (DC, rectified AC or PWM) externally and feeding it to each block. |

Just google "arduino radio module". --- End quote --- The model railroad environment is very noisy. I would expect any RF communication to be problematic. I expect his real problem is going to be physical size restrictions and the power needs. A HO locomotive requires about 1A more or less. The Arduino Nano is about 3 times bigger than most DCC controllers. |
